Review and improve UI accessibility, including color contrast, keyboard operation, visible focus, and clear status messages. A contrast checker supports color checks, while guidance also covers text zoom and form fields obscured by mobile keyboards.
Calculates the WCAG 2.x contrast ratio between two colors, grades it against the AA and AAA thresholds for body text, large text and non-text UI parts, and finds the closest shade that passes. Use when someone asks to "check the contrast", "is this text readable on this background", "does our palette meet WCAG AA", "fix the low-contrast text", "audit the design tokens for accessibility", or brings a failed contrast finding from an audit. Handles hex and rgb() values, alpha, whole palettes, light and dark themes and a CI gate.

Detects and fixes color contrast violations using WCAG 2.1 guidelines and perceptual analysis. Expert in contrast ratio calculation, color blindness simulation, and providing accessible alternatives. Activate on "check contrast", "color accessibility", "WCAG audit", "readability check", "contrast ratio", "hard to read", "can't see text". NOT for general color theory (use color-theory-palette-harmony-expert), brand color selection (use web-design-expert), or non-visual accessibility (use ux-friction-analyzer).

Diagnose and fix video/image color OBJECTIVELY with the get_image (action:"analyze_color") tool (scopes/stats such as black/white points, contrast, saturation, clipping, cast) instead of eyeballing a contact sheet. Covers the "washed out" signature, why reference color-match (mkl/ColorMatch/ColorMatchAdobe) CAN'T add contrast a flat source lacks, the levels/contrast-stretch fix (core AdjustContrast / CurveEditor), the measure→fix→re-measure loop, the side-by-side sandbox pattern, and where to place the fix in a render graph (after decode, before save). Use when a render looks washed out / flat / dull / over-saturated / color-cast, or when deciding between a color-match and a contrast/levels fix.

Check text, input borders, meaningful icons, and other interface elements for sufficient color contrast. Guide color adjustments against WCAG accessibility thresholds and verify readability across default, hover, focus, active, and visited states.
Guide slide edits with concrete rules for text size, spacing, alignment, and color contrast. Use it when replacing content or adjusting individual elements to keep pages readable and consistent with their existing design.
Set shared brand colors, fonts, layout style, and table of contents behavior for markdown-html outputs. A guided setup checks text and link contrast, derives twelve reusable CSS settings, and saves preferences globally or per project.
[Design System] Quantitative accessibility audit for UI - contrast ratios, font sizes, tap targets, heading hierarchy. Use when (1) checking WCAG color contrast compliance, (2) auditing text sizes for readability, (3) validating touch/click target sizes, (4) reviewing heading structure and landmarks, (5) user asks to 'check accessibility', 'audit contrast', 'WCAG compliance', or 'a11y check'.

Design and audit interfaces for Web, iOS, and Android using WCAG 2.2 accessibility guidance. Check screen-reader labels, keyboard navigation, contrast, and control sizes to identify barriers and guide implementation for people using assistive technology.
Supports palette creation and contrast checks using color science references. It also covers color naming, pigment mixing, and historical color theory, helping you explore color choices for design and creative work.
Review a design or web page against WCAG 2.1 AA, an accessibility standard. Organize findings on contrast, keyboard access, forms, and screen reader behavior, with severity levels and practical recommendations for fixes.
Audit web applications for accessibility issues against WCAG 2.2 Level A and AA, the web accessibility standards. Get framework-specific code fixes, contrast checks, verification steps, and reports, with options for automated checks in development pipelines.
Review a design or web page against WCAG 2.1 AA, an accessibility standard. Organize findings on contrast, keyboard access, forms, and screen reader behavior, with severity levels and practical recommendations for fixes.
Build and review interface color systems with palettes, format conversions, and semantic tokens that name colors by purpose. Measure foreground and background contrast, and identify inconsistent themes, misused color roles, and colors outside the supported range.
Shape a high-contrast interface with dark molded panels, inset shadows, and tactile controls that resemble physical objects. Apply a consistent visual system across page framing, cards, buttons, and small status displays, using one restrained accent color.
Design tokens, light/dark theming, and WCAG contrast validation for HTML documents and decks, compiled into one inlinable CSS bundle. Use when theming a report or deck, auditing contrast, or fixing dark-mode color drift.

World-class accessibility design expertise combining the inclusive design principles of Microsoft's Inclusive Design team, the technical rigor of the W3C WCAG working group, and the lived experience perspective of disability advocates. Accessibility is not a feature - it's a fundamental quality attribute that makes products usable by everyone. Great accessibility design is invisible to those who don't need it and essential to those who do. It benefits everyone: captions help in noisy environments, keyboard navigation helps power users, high contrast helps in bright sunlight. When you design for the extremes, you improve the experience for all. Accessibility is not a checklist - it's a mindset that asks "who are we excluding?" at every design decision. Use when "accessibility, a11y, wcag, screen reader, keyboard navigation, color contrast, alt text, aria, focus management, skip link, assistive technology, inclusive design, ada compliance, section 508, accessible, voiceover, nvda, jaws, tab order, focus trap, accessibility, a11y, wcag, inclusive-design, screen-reader, keyboard-navigation, color-contrast, aria, focus-management, assistive-technology" mentioned.

Check color contrast ratios against WCAG AA and AAA accessibility standards. Use when the user wants to verify if their color combinations are accessible, check contrast between text and background colors, or audit a palette for accessibility.

Load this skill whenever the project contains text, UI components, icons, form controls, data visualisations, or focus indicators — in short, almost every project. Under no circumstances hard-code colour values without verifying contrast ratios. Absolutely always ensure text meets 4.5:1, large text meets 3:1, and non-text UI elements meet 3:1 against adjacent colours. Test in light mode, dark mode, and forced-colors (high contrast) mode.

Create DESIGN.md files that combine exact design values with explanations for coding agents. Validate file structure and color contrast, compare versions, and export shared design settings to Tailwind or a standard design-token JSON format.
Design and code restrained web interfaces using warm whites, charcoal text, contrasting typefaces, and generous spacing. Flat grids, muted pastel accents, and subtle interactions create an editorial feel, with motion settings that respect user preferences.
Design web interfaces inspired by industrial print and old military terminals. Use rigid grids, contrasting type sizes, restrained color, and simulated analog textures to shape data-heavy dashboards, portfolios, or editorial sites.
