WCAG 2.1/2.2 compliance, WAI-ARIA implementation, screen reader optimization, keyboard navigation, and accessibility testing expert. Use PROACTIVELY for accessibility violations, ARIA errors, keyboard navigation issues, screen reader compatibility problems, or accessibility testing automation needs.
World-class color theory expertise combining the scientific precision of Josef Albers' "Interaction of Color," the systematic thinking of color systems from Pantone and RAL, and the perceptual psychology insights from researchers like Bevil Conway. Color is not just aesthetics - it's communication, emotion, and usability compressed into wavelengths. Great color work is invisible when done right. Users don't notice "nice colors" - they notice when they can't read text, when buttons don't look clickable, when errors don't feel urgent, or when the interface feels "off" without knowing why. Color theory is the science of making the right thing feel obvious. Use when "color theory, color palette, color scheme, color harmony, complementary colors, analogous colors, contrast ratio, dark mode colors, light mode, color tokens, semantic colors, color accessibility, color blindness, color psychology, color system, brand colors, data visualization colors, color, design, accessibility, contrast, dark-mode, theming, tokens, wcag, palette, harmony" mentioned.
Automated accessibility testing with axe-core, Playwright, and jest-axe for WCAG compliance. Use when adding or validating a11y tests, running WCAG checks, or auditing UI accessibility.
Validate WCAG 2.1 compliance, screen reader compatibility, and Universal Design for Learning (UDL) principles implementation throughout curriculum materials. Use when checking accessibility, validating UDL, or ensuring compliance. Activates on "accessibility check", "WCAG validation", "UDL review", or "screen reader test".
Accessibility (a11y) best practices for React components. Use when creating UI components, forms, interactive elements, or reviewing code for accessibility compliance.
Comprehensive design token system for typography, colors, and theming with WCAG AA compliance, TypeScript types, and framework integration (CSS-in-JS, Tailwind, CSS Variables).
Automatically applies accessibility best practices to Swift projects (SwiftUI and UIKit). Use when working on iOS/macOS projects that need VoiceOver support, Dynamic Type, WCAG compliance, or accessibility audits. Triggers on Swift accessibility tasks, a11y improvements, or when the user mentions accessibility, VoiceOver, or Dynamic Type.
Color contrast analyzer for WCAG compliance. Use when analyzing color contrast in code files, when user mentions WCAG compliance, color accessibility, contrast ratios, or when discussing colors in UI components. Calculates contrast ratios, identifies violations, and suggests accessible color alternatives that preserve design themes.
Use this skill to review implemented UI code for WCAG accessibility compliance. Triggers when reviewing components, pages, or templates for accessibility, auditing a feature after implementation, or answering questions about accessible patterns, ARIA, keyboard navigation, or screen reader support.
Audit and fix RGAA 4.1.2 accessibility issues in any web framework that outputs HTML: React, Vue, Svelte, Astro, Angular, Next.js, Nuxt, SvelteKit, plain HTML, Handlebars, ERB, Nunjucks, and similar. Activates proactively whenever a developer writes, modifies, generates, or refactors any component or template — even without explicit mention of accessibility. Triggers on: "create a component", "add a form", "refactor this header", "add a data table", "add a nav", "build a layout", "audit accessibility", "check a11y", "RGAA", "is this accessible", "make WCAG compliant", "fix accessibility issues", or any request to write/review .jsx/.tsx/.vue/.svelte/.astro/.html files. Covers static code only: images alt text, colors, tables, links, mandatory elements, information structure, forms, navigation landmarks.
Provides brand color psychology and strategic palette development frameworks including Color-in-Context Theory, 60-30-10 Rule, color harmony systems, archetype color associations, Blue Ocean color differentiation, cultural considerations, and accessibility requirements. Auto-activates during brand color selection, palette development, color psychology discussions, and color strategy work. Use when discussing brand colors, color palettes, color psychology, color differentiation, color accessibility, color harmony, WCAG compliance, or color specifications.
Sense accessibility barriers with gentle awareness. Listen to the forest, scan for obstacles, test the paths, guide toward inclusion, and protect all wanderers. Use when auditing accessibility, testing for a11y, or ensuring inclusive design.
