Purpose

What this test checks

Measure text and images of text in each meaningful state, then apply the large-text thresholds and normative exclusions.

What this result means: This WCAG 1.4.3 Contrast (Minimum) procedure determines whether the recorded targets meet WCAG 1.4.3 on web-desktop-cross-browser in the tested states. A broader conformance decision must also account for every applicable target in the declared scope, complete processes, accessibility-supported use and the other WCAG conformance requirements.

Why it matters

Detect text that does not have enough luminance contrast against its actual background. People most likely affected: people with low vision; People with colour-vision differences or reduced contrast sensitivity; People using a display in glare or other low-contrast conditions. Text, instructions, values or states may be unreadable even though they remain present in the interface. In the recorded web-desktop-cross-browser environment, apply the criterion to every relevant state and named normative exception; failures in critical tasks and complete processes carry the greatest user impact.

When to use it

Apply to visible text and images of text unless a recorded normative exclusion applies. Measure inactive components only to decide exclusion; do not treat all disabled-looking content as inactive.

Confirm before starting

Mark it not applicable only when

Exceptions

Incidental text or image of text

Decision condition
The text is part of an inactive user-interface component, pure decoration, not visible to anyone, or part of a picture containing significant other visual content.
Evidence needed
Rendered context, state evidence and explanation of the applicable incidental branch.
Common error
Small, faint, placeholder or secondary text is not automatically incidental; an author-styled disabled appearance is not enough if the control remains operable.
Scope
Only the text meeting the recorded incidental branch.

Logotype

Decision condition
The text is part of a logo or brand name.
Evidence needed
Rendered logo/brand context and identification of the text as part of the logotype.
Common error
Brand-coloured headings, slogans and ordinary product text are not automatically logotypes.
Scope
Only text that is part of the logo or brand name.

Prepare

What you need

  • The product area and test targets are agreed before testing starts.
  • The operating system, browser, viewport and input method are recorded.
  • Test data is safe to use and does not expose unnecessary personal information.

Targets and required variations

  • Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope.
  • Default, hover, focus, selected, pressed, visited, error, success and other states where text or its background changes and remains applicable.
  • Responsive, theme and background-image variations selected in scope.

Clean state

  • Start from a documented clean or known state and record pre-existing preferences, extensions and cached data that can change the result.

Assumptions: one page or component state; add another execution block for each materially different template or state

Variation: Add a new per-target execution and evidence allowance for each additional target class or state that could produce a different result. Add setup time for each distinct environment.

Excluded: Client coordination, inaccessible-environment recovery, recruitment, legal review, remediation implementation and waiting time unless the procedure states otherwise.

Execute

Test steps

Follow each action in order. The expected result is always visible; open the guidance when you need setup, tool, evidence, decision or repeat details. Step-level recording is optional while work is in progress and required only to export a completed execution.

Step 1

Inventory unique text presentations

Purpose: For WCAG 1.4.3 Contrast (Minimum), prepare the named scenario: Inventory unique text presentations. Target: Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope. The preparation must establish this result: The inventory is sufficient to explain what was measured and what was sampled.

User impact: Text, instructions, values or states may be unreadable even though they remain present in the interface. This scenario isolates that risk in the action named Inventory unique text presentations.

Identify each unique foreground, background, font size, font weight and meaningful state for visible text and images of text. Include gradients, background images and changing interactive states.

Expected result

The inventory is sufficient to explain what was measured and what was sampled.

Failure observation

During WCAG 1.4.3 Contrast (Minimum), the target, starting state, environment or scope record remains ambiguous for the scenario named Inventory unique text presentations. The preparation result cannot be demonstrated: The inventory is sufficient to explain what was measured and what was sampled.

Setup, evidence and decision guidance
Target
Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope.
Required state
Every selected theme, viewport and meaningful state.
Tool or command
Rendered-page inspection, stylesheet inspection and a contrast inventory.
Record
Target text, page/state, font metrics, foreground/background source and sampling rationale.
Pass
Record passed for the WCAG 1.4.3 Contrast (Minimum) scenario named Inventory unique text presentations only when the evidence (Target text, page/state, font metrics, foreground/background source and sampling rationale.) supports: The inventory is sufficient to explain what was measured and what was sampled.
Fail
Record failed when the action is completed and this failure observation is reproduced: During WCAG 1.4.3 Contrast (Minimum), the target, starting state, environment or scope record remains ambiguous for the scenario named Inventory unique text presentations. The preparation result cannot be demonstrated: The inventory is sufficient to explain what was measured and what was sampled.
Not applicable
No visible text or image of text in the selected subject matches the criterion's applicability.
Blocked
Record blocked, not passed, when The target is applicable, but a required state, environment, action or evidence item was not completed.
Repeat or recover
Repeat when text styling, imagery, state colours or themes change.
Limitations
This WCAG 1.4.3 Contrast (Minimum) scenario covers only the action named Inventory unique text presentations for the recorded target and state. It contributes evidence to 1.4.3; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
Sample repeated styles only when the computed colours and background conditions are genuinely equivalent.
Record this step

Step 2

Classify size and exclusions

Purpose: For WCAG 1.4.3 Contrast (Minimum), execute the named scenario: Classify size and exclusions. Target: Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope. Compare the observation with this result: Each target has a documented threshold—4.5:1 or 3:1—or a supported exclusion.

User impact: Text, instructions, values or states may be unreadable even though they remain present in the interface. This scenario isolates that risk in the action named Classify size and exclusions.

Determine whether each target is normal or large-scale text. Treat text as large-scale at 24 CSS pixels regular, or approximately 18.66 CSS pixels with a bold weight. Evaluate incidental and logotype exclusions before the ratio decision.

Expected result

Each target has a documented threshold—4.5:1 or 3:1—or a supported exclusion.

Failure observation

After the tester completes the WCAG 1.4.3 Contrast (Minimum) scenario named Classify size and exclusions, the recorded observation for the target is inconsistent with the required result: Each target has a documented threshold—4.5:1 or 3:1—or a supported exclusion.

Setup, evidence and decision guidance
Target
Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope.
Required state
Rendered font size and weight used by the target in the measured state.
Tool or command
Computed-style inspection and rendered context.
Record
Computed size, weight, threshold and any exclusion evidence.
Pass
Record passed for the WCAG 1.4.3 Contrast (Minimum) scenario named Classify size and exclusions only when the evidence (Computed size, weight, threshold and any exclusion evidence.) supports: Each target has a documented threshold—4.5:1 or 3:1—or a supported exclusion.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 1.4.3 Contrast (Minimum) scenario named Classify size and exclusions, the recorded observation for the target is inconsistent with the required result: Each target has a documented threshold—4.5:1 or 3:1—or a supported exclusion.
Not applicable
No visible text or image of text in the selected subject matches the criterion's applicability.
Blocked
Record blocked, not passed, when The target is applicable, but a required state, environment, action or evidence item was not completed.
Repeat or recover
Reclassify when responsive styles change size or weight.
Limitations
This WCAG 1.4.3 Contrast (Minimum) scenario covers only the action named Classify size and exclusions for the recorded target and state. It contributes evidence to 1.4.3; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
A large typeface shape does not lower the threshold unless the rendered size and weight meet the definition.
Record this step

Step 3

Sample actual colours

Purpose: For WCAG 1.4.3 Contrast (Minimum), execute the named scenario: Sample actual colours. Target: Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope. Compare the observation with this result: The colour pair represents the authored text and the least favourable relevant background.

User impact: Text, instructions, values or states may be unreadable even though they remain present in the interface. This scenario isolates that risk in the action named Sample actual colours.

Obtain the specified or underlying foreground and actual background colours. For gradients and images, measure the least favourable relevant areas behind the glyphs. Do not use anti-aliased edge pixels as the authored text colour.

Expected result

The colour pair represents the authored text and the least favourable relevant background.

Failure observation

After the tester completes the WCAG 1.4.3 Contrast (Minimum) scenario named Sample actual colours, the recorded observation for the target is inconsistent with the required result: The colour pair represents the authored text and the least favourable relevant background.

Setup, evidence and decision guidance
Target
Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope.
Required state
Exact rendered state used for the decision.
Tool or command
Colour picker plus computed styles or source-image inspection; record the tool and version.
Record
Foreground/background values, sample locations and screenshots for variable backgrounds.
Pass
Record passed for the WCAG 1.4.3 Contrast (Minimum) scenario named Sample actual colours only when the evidence (Foreground/background values, sample locations and screenshots for variable backgrounds.) supports: The colour pair represents the authored text and the least favourable relevant background.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 1.4.3 Contrast (Minimum) scenario named Sample actual colours, the recorded observation for the target is inconsistent with the required result: The colour pair represents the authored text and the least favourable relevant background.
Not applicable
No visible text or image of text in the selected subject matches the criterion's applicability.
Blocked
Record blocked, not passed, when The target is applicable, but a required state, environment, action or evidence item was not completed.
Repeat or recover
Repeat across every material gradient stop, image region or animated background state.
Limitations
This WCAG 1.4.3 Contrast (Minimum) scenario covers only the action named Sample actual colours for the recorded target and state. It contributes evidence to 1.4.3; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
Browser anti-aliasing can make edge pixels lighter or darker; base the calculation on the underlying declared colours where available.
Record this step

Step 4

Calculate without rounding

Purpose: For WCAG 1.4.3 Contrast (Minimum), execute the named scenario: Calculate without rounding. Target: Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope. Compare the observation with this result: The unrounded ratio meets or exceeds the applicable threshold.

User impact: Text, instructions, values or states may be unreadable even though they remain present in the interface. This scenario isolates that risk in the action named Calculate without rounding.

Calculate the WCAG contrast ratio. Compare the unrounded result with 4.5:1 for normal text or 3:1 for large-scale text and images of text.

Expected result

The unrounded ratio meets or exceeds the applicable threshold.

Failure observation

After the tester completes the WCAG 1.4.3 Contrast (Minimum) scenario named Calculate without rounding, the recorded observation for the target is inconsistent with the required result: The unrounded ratio meets or exceeds the applicable threshold.

Setup, evidence and decision guidance
Target
Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope.
Required state
Colour pair and threshold established in S2–S3.
Tool or command
A WCAG contrast calculator that exposes input colours and adequate precision.
Record
Tool/version, input values, unrounded ratio and threshold.
Pass
Record passed for the WCAG 1.4.3 Contrast (Minimum) scenario named Calculate without rounding only when the evidence (Tool/version, input values, unrounded ratio and threshold.) supports: The unrounded ratio meets or exceeds the applicable threshold.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 1.4.3 Contrast (Minimum) scenario named Calculate without rounding, the recorded observation for the target is inconsistent with the required result: The unrounded ratio meets or exceeds the applicable threshold.
Not applicable
No visible text or image of text in the selected subject matches the criterion's applicability.
Blocked
Record blocked, not passed, when The target is applicable, but a required state, environment, action or evidence item was not completed.
Repeat or recover
Recalculate after any colour or threshold classification change.
Limitations
This WCAG 1.4.3 Contrast (Minimum) scenario covers only the action named Calculate without rounding for the recorded target and state. It contributes evidence to 1.4.3; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
A measured ratio is not the final result until applicability, size and exclusion decisions are also recorded.
Record this step

Step 5

Repeat material variations and recovery

Purpose: For WCAG 1.4.3 Contrast (Minimum), execute the named scenario: Repeat material variations and recovery. Target: Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope. Compare the observation with this result: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.

User impact: Text, instructions, values or states may be unreadable even though they remain present in the interface. This scenario isolates that risk in the action named Repeat material variations and recovery.

Repeat the WCAG 1.4.3 Contrast (Minimum) action for each inventoried variation that can change the outcome. Include relevant default, revealed, error, interruption, recovery and confirmation states and complete the selected process from start to finish where this test can affect task completion.

Expected result

Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.

Failure observation

After the tester completes the WCAG 1.4.3 Contrast (Minimum) scenario named Repeat material variations and recovery, the recorded observation for the target is inconsistent with the required result: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.

Setup, evidence and decision guidance
Target
Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope.
Required state
For WCAG 1.4.3 Contrast (Minimum): Default, hover, focus, selected, pressed, visited, error, success and other states where text or its background changes and remains applicable. Responsive, theme and background-image variations selected in scope.
Tool or command
For WCAG 1.4.3 Contrast (Minimum), use the same recorded method, then change only the state, environment or recovery condition being compared.
Record
Variation identifier; changed state or environment; start and end points; actual observation; recovery result; intervention; evidence reference and target outcome.
Pass
Record passed for the WCAG 1.4.3 Contrast (Minimum) scenario named Repeat material variations and recovery only when the evidence (Variation identifier; changed state or environment; start and end points; actual observation; recovery result; intervention; evidence reference and target outcome.) supports: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 1.4.3 Contrast (Minimum) scenario named Repeat material variations and recovery, the recorded observation for the target is inconsistent with the required result: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.
Not applicable
No visible text or image of text in the selected subject matches the criterion's applicability.
Blocked
Record blocked, not passed, when The target is applicable, but a required state, environment, action or evidence item was not completed.
Repeat or recover
Repeat this action for every required variation of Measure minimum text contrast and after a material target, content, state, environment or configuration change. Preserve the original observation.
Limitations
This WCAG 1.4.3 Contrast (Minimum) scenario covers only the action named Repeat material variations and recovery for the recorded target and state. It contributes evidence to 1.4.3; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
For WCAG 1.4.3 Contrast (Minimum), change one material condition at a time where practical. Do not assume that a passing default state covers errors, overlays, orientation changes, interruptions or recovery.
Record this step

Decide

How to decide

Passed

Each applicable normal-text presentation has an unrounded contrast ratio of at least 4.5:1, and each applicable large-scale presentation has at least 3:1, or a documented normative exclusion applies.

Failed

An applicable text or image-of-text presentation has a ratio below its threshold and no normative exclusion applies.

Not applicable
No visible text or image of text in the selected subject matches the criterion's applicability.
Cannot tell
The actual foreground/background pair, size classification or exclusion cannot be determined after reasonable investigation.
Not tested
The target is applicable, but a required state, environment, action or evidence item was not completed.
Aggregation and reporting boundaries

Aggregation: Preserve results per unique presentation and state. One failure prevents a passed aggregate; cantTell and untested remain unresolved.

WCAG decision: A WCAG 1.4.3 satisfied decision requires coverage of all applicable content in the conformance scope and the WCAG conformance requirements. A sampled procedure must disclose coverage limitations.

Automation: A passed ACT result or automated scan does not cover all images of text, gradients, background images, meaningful states or exclusion judgements. A passed automated or ACT result must never set the criterion to satisfied automatically.

Worked example and outcome calibration

A11Y-WCAG-014-WORKED-001: representative worked example

Context: Representative synthetic example for WCAG 1.4.3 Contrast (Minimum) on a fictional, version-frozen product target; no client or participant execution occurred.

Inspected: The tester follows S2 (Classify size and exclusions) using the target, required state, tool and repeat rule stated in this procedure.

Observed output: After the tester completes the WCAG 1.4.3 Contrast (Minimum) scenario named Classify size and exclusions, the recorded observation for the target is inconsistent with the required result: Each target has a documented threshold—4.5:1 or 3:1—or a supported exclusion.

Evidence:

  • example-evidence-001: target and state record for Each unique text or image-of-text foreground/background combination, size, weight and meaningful state in the selected scope.
  • example-evidence-002: contemporaneous observation from the named method — Computed size, weight, threshold and any exclusion evidence.
  • example-evidence-003: comparison note linking the actual observation to the expected result and claim boundary

Tester reasoning: The recorded observation does not demonstrate the expected result: Each target has a documented threshold—4.5:1 or 3:1—or a supported exclusion. The failed decision is limited to this synthetic target and state; unexecuted coverage is not inferred.

Decision: failed

Finding: A11Y-WCAG-014-example-finding-001 — Measure minimum text contrast: expected result is not demonstrated. The represented barrier may affect People with low vision.; People with colour-vision differences or reduced contrast sensitivity.; People using a display in glare or other low-contrast conditions.

Remediation: Change the represented target or process so it demonstrates this result: Each target has a documented threshold—4.5:1 or 3:1—or a supported exclusion. Then rerun the affected step and every dependent variation.

Reviewer feedback: The reviewer confirms applicability, environment, actual-versus-expected comparison, evidence references and bounded wording; unsupported product-wide or conformance language is removed.

Final client wording: Synthetic training finding: the sampled Measure minimum text contrast target does not meet the procedure expectation in the recorded state. User impact and broader scope require evidence from the buyer's real execution.

Retest: Synthetic retest example: after the represented change, repeat the failed step plus material error and recovery states. Close the finding only when new evidence demonstrates the expected result; otherwise retain the non-pass outcome.

Boundary: This is a representative, synthetic worked example for training and calibration. It is not evidence from a client product, participant or real assistive-technology execution.

Outcome calibration

Passed
16 CSS-pixel body text uses #1F1F1F on #FFFFFF and the recorded unrounded ratio exceeds 4.5:1.

Normal text meets the correct threshold.

Failed
16 CSS-pixel error text uses a red/white pair with an unrounded ratio below 4.5:1.

The meaningful error state is applicable and fails the normal-text threshold.

Not applicable
A selected decorative canvas contains no visible text or image of text.

No target matches this procedure; meaningful graphics require a different check.

Cannot tell
Text is composited over a cross-origin animated background and the least favourable background colour cannot be captured.

The colour pair cannot be determined defensibly.

Not tested
Default text was measured, but the selected error and visited states were not.

Applicable meaningful states remain untested.

Passed
Text forming part of a recorded company logotype is below 4.5:1.

The ratio is below the normal threshold, but the logotype exclusion applies only to that text.

Sampling, complete processes and platform limitations

Test every in-scope instance when practical. For a large population, document a sample that includes each template, content or control type, meaningful state and high-risk task.

If this check is part of a user journey, test the selected journey from start to finish, including relevant errors and recovery. Record any path that was not tested.

  • Check relevant browser, tool or assistive-technology release notes before assigning unexpected behaviour to the product.
  • If responsibility is unclear, record the reproducible behaviour and use cannot tell until it is resolved.

ACT rules and WCAG technique traceability

This is a project-authored manual procedure, not a W3C Approved ACT Rule. An ACT result can support only the part of this procedure covered by that rule. It does not replace the remaining manual or assistive-technology checks.

  • Text has minimum contrast afw4f7

    Supports measurable text-contrast coverage within the rule's applicability. Manual review is still needed for exclusions, images of text and untested states.
