# Color Psychology — Color Psychology Methodology

Expert knowledge used by the visual-director agent when designing brand color systems.

## Why Color Defines a Brand

Color is perceived before the logo. Research shows that **62-90% of consumers form their first impression based on color alone**. Coca-Cola's red, Tiffany's teal, Starbucks' green — color is brand.

## Building a Brand Color Palette

### The 60-30-10 Rule

| Ratio | Role | Use |
|-------|------|-----|
| **60%** | Primary Color | Backgrounds, large areas |
| **30%** | Secondary Color | Section dividers, highlighted areas |
| **10%** | Accent Color | CTA buttons, key elements |

### Palette Composition Types

| Type | Color Relationship | Feel | Suited For |
|------|-------------------|------|-----------|
| **Monochromatic** | Lightness/saturation variations of one color | Refined, consistent | Minimal, luxury |
| **Analogous** | 3-4 adjacent colors on the color wheel | Harmonious, stable | Nature, wellness |
| **Complementary** | Opposite sides of the color wheel | Contrasting, energetic | Sports, entertainment |
| **Split-Complementary** | Two colors flanking the complement | Contrast + stability | Versatile |
| **Triadic** | 120-degree intervals on the color wheel | Vibrant, diverse | Children, creative |

### Palette Design Process

1. **Extract emotional keywords from brand essence**: "Trust + Innovation" -> Blue family + orange as accent
2. **Analyze competitor colors**: Avoid identical colors or differentiate intentionally
3. **Determine primary color**: Select the optimal color from the emotion matrix
4. **Determine palette type**: Choose composition matching brand personality
5. **Verify accessibility**: Ensure WCAG AA contrast ratios or higher
6. **Test across applications**: Test on logos, web, print, social media, and all touchpoints

## Color Accessibility Standards

| Standard | Contrast Ratio | Use |
|----------|---------------|-----|
| **WCAG AA** | 4.5:1 (body text), 3:1 (large text) | Minimum requirement |
| **WCAG AAA** | 7:1 (body text), 4.5:1 (large text) | Recommended standard |

### Accessibility Checklist
