SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you create and refine brand and UI color palettes while ensuring accessibility by validating contrast ratios against WCAG requirements.

Core Features & Use Cases

  • Accessible palette generation: Produce cohesive brand colors (primary, secondary, accent), semantic colors (success/warning/error/info), and a neutral scale with exact hex/RGB/HSL values.
  • Contrast verification: Check foreground/background combinations and label results as AA/AAA/Fail.
  • Dark mode creation and adjustments: Generate dark mode equivalents that adjust brightness and saturation rather than simply inverting colors.

Quick Start

Provide a primary base hex color and describe the brand personality, then ask for an accessible palette with dark mode and WCAG contrast checks.

FAQPage Schema
How do I generate an accessible color palette from a base hex color?

To generate an accessible color palette, provide a primary base hex color and describe your brand personality. The system produces cohesive brand, semantic, and neutral colors with exact hex, RGB, and HSL values.

Can I check if my UI color combinations meet WCAG AA or AAA contrast requirements?

You can verify foreground and background color combinations for WCAG compliance. The contrast check evaluates specific color pairs and labels the results as AA, AAA, or Fail based on accessibility requirements.

How does dark mode generation handle existing brand colors?

Dark mode generation adjusts brightness and saturation for dark mode equivalents rather than simply inverting colors. This creates a visually cohesive dark theme while maintaining the original brand identity and accessibility.

What color scales and semantic tokens are included in a generated theme?

A generated theme includes primary, secondary, and accent brand colors, a neutral scale, and semantic colors for success, warning, error, and info states. These are output as structured semantic color tokens.

Can I audit specific color contrast pairs for accessibility compliance?

You can audit specific color contrast pairs by providing the foreground and background colors. The system evaluates the contrast ratio and labels the combination as passing AA, passing AAA, or failing WCAG requirements.

What's the best way to adjust an existing design system theme for better contrast?

To adjust an existing design system theme, provide your current colors and request WCAG contrast checks. The system audits foreground and background combinations and generates accessible alternatives with verified contrast ratios.
