Color Theory

Systematic color design -- from strategic color selection to accessible dark mode.

Scope

Use this skill when: You are defining color schemes, building palettes, checking contrasts, designing dark mode, establishing semantic colors, creating design tokens for colors, or auditing existing color concepts for quality.

Principles

1. Colors Are Communication -- Not Decoration

Every color conveys a message. Color selection is a strategic decision.

2. Fewer Colors -- Stronger Impact

2-4 colors are sufficient for 95% of all projects. Primary color + accent color + neutral tones.

3. Contrast Is Mandatory

Without sufficient contrast, colors are ineffective. Contrast determines readability, hierarchy, and accessibility.
