Color Palette Generator Skill

Purpose

Generate accessible color palettes that comply with WCAG contrast requirements, create color scales, and export to design token formats.

Capabilities

• Create color scales from base colors
• Generate complementary, analogous, and triadic color schemes
• Ensure WCAG 2.1 AA/AAA contrast compliance
• Export palettes to design token formats (CSS, SCSS, JSON)
• Generate dark mode color variants
• Calculate color contrast ratios
• Suggest accessible color alternatives

Target Processes

• design-system.js
• component-library.js (colorSystemDesignTask)
• accessibility-audit.js

Integration Points

• chroma.js for color manipulation
• color-contrast-checker for WCAG validation
• Style Dictionary for token export
