Purpose

What this test checks

Checks contrast theme: dusk without relying on browser-only CSS emulation.

What this result means: This procedure records how Contrast Theme: Dusk behaves on windows-forced-colors-edge. It can expose evidence relevant to WCAG 1.4.1, 1.4.3, 1.4.11 and 2.4.7 for the tested task and environment. Use the linked conformance procedures for WCAG 1.4.1, 1.4.3, 1.4.11 and 2.4.7 to assess the complete requirements across the declared conformance scope.

Why it matters

Checks contrast theme: dusk without relying on browser-only CSS emulation. People most likely affected: people with low vision or colour-perception differences who use system contrast themes. Information, boundaries, focus, selection or status may disappear or become indistinguishable. In the recorded windows-forced-colors-edge environment, inspect selected, focused, disabled, error and chart states in the named system themes; removed backgrounds and substituted colours can erase boundaries or state differences.

When to use it

Apply Contrast Theme: Dusk when the frozen web-content scope rendered with the named Windows Contrast Theme and forced colours active. The selected focus is Dusk.

Confirm before starting

Mark it not applicable only when

Exceptions

This platform, journey, usability or quality procedure creates no additional normative exception. Apply exceptions only in the linked atomic or criterion-level conformance procedure and preserve that separate decision.

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 selected control, graphic and meaningful state relevant to Dusk.
  • Default, revealed, loading, empty, validation error, interruption, recovery and confirmation where meaningful.
  • Every required environment, viewport, orientation, language and authenticated state recorded in the frozen scope.

Clean state

  • Complete a known-good calibration in the same environment before product testing.
  • Start from a recorded clean or known state and preserve any prior preferences, extensions, cache or profile settings that can affect output.

Assumptions: one page in one Windows contrast theme; add themes only when product colours or assets respond differently

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

Prepare the scope, target and environment

Purpose: For Contrast Theme: Dusk, prepare the named scenario: Prepare the scope, target and environment. Target: Each selected control, graphic and meaningful state relevant to Dusk. The preparation must establish this result: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.

User impact: Information, boundaries, focus, selection or status may disappear or become indistinguishable. This scenario isolates that risk in the action named Prepare the scope, target and environment.

Before executing Contrast Theme: Dusk, freeze the product version and scope. Inventory each applicable target, select the required starting states, prepare safe test data and record every required environment value. Complete any named known-good calibration before attributing an observation to the product.

Expected result

The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.

Failure observation

During Contrast Theme: Dusk, the target, starting state, environment or scope record remains ambiguous for the scenario named Prepare the scope, target and environment. The preparation result cannot be demonstrated: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.

Setup, evidence and decision guidance
Target
Each selected control, graphic and meaningful state relevant to Dusk.
Required state
For Contrast Theme: Dusk, the product version and scope are frozen; every selected target and material starting state is uniquely identified.
Tool or command
Use the scope record and worksheet environment fields for Contrast Theme: Dusk: operating_system, operating_system_version, browser, browser_version, viewport_css_pixels, input_method, contrast_theme.
Record
Scope/version reference; target inventory; starting states; safe-data reference; every required environment value; calibration result or reason it is not required.
Pass
Record passed for the Contrast Theme: Dusk scenario named Prepare the scope, target and environment only when the evidence (Scope/version reference; target inventory; starting states; safe-data reference; every required environment value; calibration result or reason it is not required.) supports: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.
Fail
Record failed when the action is completed and this failure observation is reproduced: During Contrast Theme: Dusk, the target, starting state, environment or scope record remains ambiguous for the scenario named Prepare the scope, target and environment. The preparation result cannot be demonstrated: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.
Not applicable
The frozen scope contains no rendered content or state relevant to Dusk.
Blocked
Record blocked, not passed, when An applicable target, required state, complete process or named real environment was not executed.
Repeat or recover
For Contrast Theme: Dusk, correct the setup gap, preserve the original blocked record and start a new execution observation before proceeding.
Limitations
This scenario records the action named Prepare the scope, target and environment for Contrast Theme: Dusk in windows-forced-colors-edge. It does not establish behaviour for another target, state or environment and does not set a WCAG conformance decision.
If you are new to this test
For Contrast Theme: Dusk, do not begin from an undocumented browser tab, document copy, device state, participant plan or evidence set. Record the exact item you will test first.
Record this step

Step 2

Record Windows build, Edge build, active contrast theme and display scale

Purpose: For Contrast Theme: Dusk, execute the named scenario: Record Windows build, Edge build, active contrast theme and display scale. Target: Each selected control, graphic and meaningful state relevant to Dusk. Compare the observation with this result: The operating-system forced-colours environment is reproducible.

User impact: Information, boundaries, focus, selection or status may disappear or become indistinguishable. This scenario isolates that risk in the action named Record Windows build, Edge build, active contrast theme and display scale.

Record Windows build, Edge build, active contrast theme and display scale; save the default-state comparison.

Expected result

The operating-system forced-colours environment is reproducible.

Failure observation

After the tester completes the Contrast Theme: Dusk scenario named Record Windows build, Edge build, active contrast theme and display scale, the recorded observation for the target is inconsistent with the required result: The operating-system forced-colours environment is reproducible.

Setup, evidence and decision guidance
Target
Each selected control, graphic and meaningful state relevant to Dusk.
Required state
For Contrast Theme: Dusk, begin in the recorded default state for the selected Dusk target before this action; preserve the exact content, account, platform and configuration used.
Tool or command
In windows-forced-colors-edge, In Windows Settings, activate the recorded Contrast Theme, then use the named browser without forced-colour emulation. Compare the default rendering with the active system theme and inspect focus, selected, disabled, error and success states.
Record
Windows, Edge, contrast-theme, display-scale and zoom versions/settings.
Pass
Record passed for the Contrast Theme: Dusk scenario named Record Windows build, Edge build, active contrast theme and display scale only when the evidence (Windows, Edge, contrast-theme, display-scale and zoom versions/settings.) supports: The operating-system forced-colours environment is reproducible.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the Contrast Theme: Dusk scenario named Record Windows build, Edge build, active contrast theme and display scale, the recorded observation for the target is inconsistent with the required result: The operating-system forced-colours environment is reproducible.
Not applicable
The frozen scope contains no rendered content or state relevant to Dusk.
Blocked
Record blocked, not passed, when An applicable target, required state, complete process or named real environment was not executed.
Repeat or recover
Repeat with at least one light and one dark Windows Contrast Theme and for every meaningful interactive state represented by the target. Preserve the first Contrast Theme: Dusk observation when repeating.
Limitations
This scenario records the action named Record Windows build, Edge build, active contrast theme and display scale for Contrast Theme: Dusk in windows-forced-colors-edge. It does not establish behaviour for another target, state or environment and does not set a WCAG conformance decision.
If you are new to this test
For Contrast Theme: Dusk: Do not judge the original CSS colours. Check whether system colours preserve boundaries, meaning and state when author backgrounds and images are substituted or removed.
Record this step

Step 3

Step 6

Repeat material variations and recovery

Purpose: For Contrast Theme: Dusk, execute the named scenario: Repeat material variations and recovery. Target: Each selected control, graphic and meaningful state relevant to Dusk. 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: Information, boundaries, focus, selection or status may disappear or become indistinguishable. This scenario isolates that risk in the action named Repeat material variations and recovery.

Repeat the Contrast Theme: Dusk 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 Contrast Theme: Dusk 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 selected control, graphic and meaningful state relevant to Dusk.
Required state
For Contrast Theme: Dusk: Default, revealed, loading, empty, validation error, interruption, recovery and confirmation where meaningful. Every required environment, viewport, orientation, language and authenticated state recorded in the frozen scope.
Tool or command
For Contrast Theme: Dusk, 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 Contrast Theme: Dusk 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 Contrast Theme: Dusk 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
The frozen scope contains no rendered content or state relevant to Dusk.
Blocked
Record blocked, not passed, when An applicable target, required state, complete process or named real environment was not executed.
Repeat or recover
Repeat this action for every required variation of Contrast Theme: Dusk and after a material target, content, state, environment or configuration change. Preserve the original observation.
Limitations
This scenario records the action named Repeat material variations and recovery for Contrast Theme: Dusk in windows-forced-colors-edge. It does not establish behaviour for another target, state or environment and does not set a WCAG conformance decision.
If you are new to this test
For Contrast Theme: Dusk, 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

Text and controls remain readable; boundaries, focus, selection, errors, status and meaningful graphics remain distinguishable without hard-coded colour loss.

Failed

An applicable Dusk target has a reproducible material barrier against one or more stated expectations; identify the exact expectation, state and evidence.

Not applicable
The frozen scope contains no rendered content or state relevant to Dusk.
Cannot tell
The target is applicable, but conflicting evidence or unresolved responsibility prevents a defensible expectation decision after recorded comparison.
Not tested
An applicable target, required state, complete process or named real environment was not executed.
Aggregation and reporting boundaries

Aggregation: Preserve every target/environment outcome. Any failed target prevents an overall passed procedure result. cantTell and untested remain unresolved; inapplicable is valid only when the completed inventory contains no applicable target.

WCAG decision: This specialist, platform, document, usability or quality result does not set a WCAG success criterion to satisfied or not_satisfied automatically. Use linked atomic and criterion-level procedures for that separate decision.

Automation: A checker, accessibility-tree inspection, emulator or simulated assistive technology is diagnostic evidence only. Complete every required manual, real-platform, contextual and exception check.

Worked example and outcome calibration

A11Y-COLOR-003-WORKED-001: representative worked example

Context: Representative synthetic example for Contrast Theme: Dusk on a fictional, version-frozen product target; no client or participant execution occurred.

Inspected: The tester follows S2 (Record Windows build, Edge build, active contrast theme and display scale) using the target, required state, tool and repeat rule stated in this procedure.

Observed output: After the tester completes the Contrast Theme: Dusk scenario named Record Windows build, Edge build, active contrast theme and display scale, the recorded observation for the target is inconsistent with the required result: The operating-system forced-colours environment is reproducible.

Evidence:

  • example-evidence-001: target and state record for Each selected control, graphic and meaningful state relevant to Dusk.
  • example-evidence-002: contemporaneous observation from the named method — Windows, Edge, contrast-theme, display-scale and zoom versions/settings.
  • 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: The operating-system forced-colours environment is reproducible. The failed decision is limited to this synthetic target and state; unexecuted coverage is not inferred.

Decision: failed

Finding: A11Y-COLOR-003-example-finding-001 — Contrast Theme: Dusk: expected result is not demonstrated. The represented barrier may affect People with low vision or colour-perception differences who use system contrast themes.

Remediation: Change the represented target or process so it demonstrates this result: The operating-system forced-colours environment is reproducible. 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 Contrast Theme: Dusk 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
In windows-forced-colors-edge, the selected Dusk target completes the recorded action and meets this expectation: Text and controls remain readable; boundaries, focus, selection, errors, status and meaningful graphics remain distinguishable without hard-coded colour loss.

The example is a calibration scenario, not an execution or approval.

Failed
An applicable Dusk target produces a reproducible barrier during the named action, with the exact state and affected user task recorded.

A failed target remains failed even if another environment or target passes.

Not applicable
The frozen scope contains no rendered content or state relevant to Dusk.

Inapplicable requires a completed inventory showing that no target matches applicability; a missing environment is not inapplicable.

Cannot tell
The Dusk target is applicable, but conflicting product/platform evidence or missing authoritative information prevents a defensible responsibility or expectation decision.

Record the conflict, comparisons attempted and person or evidence needed to resolve it.

Not tested
The Dusk target is applicable, but a required state, complete process or real environment was not executed.

Untested remains incomplete and cannot be converted to passed or inapplicable.

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.

  • One contrast theme does not represent every user colour choice. Browser emulation is diagnostic only unless the procedure explicitly says otherwise.
  • 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.
