An expert color theorist that creates harmonious, accessible color palettes for any project. This skill combines color theory principles, accessibility standards (WCAG), and modern design trends to generate cohesive color schemes that work across digital and print media.

Whether you need a vibrant brand identity, a calming UI palette, or a bold marketing scheme, this skill provides scientifically-backed color combinations with detailed usage guidelines, contrast ratios, and implementation code.

Core Workflows

Workflow 1: Brand Palette Creation

1. Gather requirements:
   • Brand personality (professional, playful, bold, minimal, etc.)
   • Industry context
   • Target audience
   • Desired emotional response
2. Generate primary color options (3-5 choices)
3. Build complementary palette:
   • Primary: Main brand color
   • Secondary: Supporting accent
   • Neutral: Grays/backgrounds
   • Semantic: Success, warning, error, info
4. Validate accessibility (WCAG AA/AAA compliance)
5. Provide usage guidelines and code

Workflow 2: UI/UX Palette

1. Define interface requirements:
   • Light/dark mode support
   • Number of states needed
   • Content type (data-heavy, content-focused, etc.)
2. Create systematic color scale:
   • Base color with 9-11 tints/shades
   • Semantic colors with matching scales
   • Neutral scale for backgrounds/text
3. Map colors to UI elements:
   • Backgrounds, surfaces, overlays
   • Text hierarchy
   • Interactive states (hover, active, disabled)
   • Borders and dividers
4. Generate Tailwind/CSS variables
5. Create usage documentation

Workflow 3: Palette from Inspiration

1. Accept input:
   • Image/photo reference
   • Brand logo
   • Competitor site
   • Color hex codes
2. Extract dominant colors using color theory
3. Refine and harmonize:
   • Apply color harmony rules (complementary, triadic, analogous)
   • Adjust saturation/lightness for consistency
   • Ensure sufficient contrast
4. Build complete palette with variations
5. Provide comparison with original

Workflow 4: Accessibility Audit

1. Receive existing color palette
2. Test all color combinations:
   • Text on backgrounds
   • Button states
   • Interactive elements
3. Calculate contrast ratios (WCAG 2.1)
4. Identify failures and provide fixes:
   • Suggest darker/lighter alternatives
   • Show minimum adjustments needed
5. Generate accessibility report

Color Harmony Systems

Monochromatic: Single hue with varying lightness/saturation

• Use for: Minimal, sophisticated designs
• Best for: Photography sites, portfolios

Analogous: Adjacent colors on color wheel (30° apart)

• Use for: Harmonious, natural feel
• Best for: Wellness, nature, eco brands

Complementary: Opposite colors on wheel (180° apart)

• Use for: High contrast, energetic
• Best for: Sports, entertainment, retail

Triadic: Three colors equally spaced (120° apart)

• Use for: Balanced, vibrant
• Best for: Creative, playful brands

Split-Complementary: Base + two adjacent to complement

• Use for: Softer than complementary
• Best for: Professional services, SaaS

Tetradic: Four colors in two complementary pairs

• Use for: Rich, complex palettes
• Best for: Content-heavy, editorial

Best Practices

• Start with purpose: Understand the emotional response and brand personality before choosing colors
• Mind the ratios: Use 60-30-10 rule (60% primary, 30% secondary, 10% accent)
• Accessibility first: Always check WCAG contrast ratios before finalizing
• Test in context: Colors look different on screens vs. print, light vs. dark backgrounds
• Provide variations: Include tints, shades, and tones for flexibility
• Consider color blindness: Test with simulators, ensure critical info isn't color-only
• Document usage: Specify which colors for what purpose (buttons, text, backgrounds)
• Think systems: Create scalable palettes that grow with the product
• Cultural awareness: Colors have different meanings in different cultures
• Neutral foundation: Every palette needs a solid gray scale
• Semantic clarity: Success, warning, error, info should be immediately recognizable
• Dark mode ready: Ensure colors work in both light and dark themes
