# Color Palette Builder

You build palettes that work in every context — UI, print, motion, marketing. Math + perception.

## When to activate
AZ: "rəng palet", "color theme", "brand colors", "dark mode rəngləri"
EN: "color palette", "color theme", "brand colors", "dark mode colors", "color scheme"

## Color relationships (color wheel)

| Type | Description | Use case |
|---|---|---|
| **Monochromatic** | Same hue, varied saturation/lightness | Minimal, focused |
| **Analogous** | 3 neighbors on wheel | Calm, harmonious |
| **Complementary** | Opposite hues | High energy, CTA |
| **Triadic** | 3 evenly spaced (120°) | Playful, balanced |
| **Tetradic** | 4 colors, 2 complementary pairs | Rich systems |
| **Split-complementary** | Base + 2 adjacent to complement | Softer than full complement |

## Palette structure (production)

```
PRIMARY      — hero color, most recognizable
SECONDARY    — support, second prominence
ACCENT       — CTA, energy moments
NEUTRAL Dark — body text, dark surfaces
NEUTRAL Mid  — borders, dividers
NEUTRAL Light— backgrounds
WHITE / OFF-WHITE
SEMANTIC:
  Success (green)
  Warning (amber)
  Error (red)
  Info (blue)
```

10 colors total for production systems.

## Accessibility (WCAG 2.2 AA mandatory)

| Pair | Min ratio |
|---|---|
| Text (small) on bg | **4.5:1** |
| Text (large 18pt+) on bg | **3:1** |
| Non-text (icons, borders) | **3:1** |
| Focus indicators | **3:1** |

Tools:
- WebAIM Contrast Checker
- Adobe Color
- Stark (Figma plugin)

## Color-blind safe checks

- Deuteranopia (red-green) — most common
- Protanopia (red weakness)
- Tritanopia (blue-yellow)

Never use color alone to convey meaning (add icon, label).

## Saturation rules

For 5-color brand: all colors should sit within ±15% saturation. Mixed pastels + vibrants break visual rhythm.

## Tonal scales (each color → 10 shades)

```
50:   lightest tint (backgrounds)
100:  very light (cards)
200:  light (subtle bg)
300:  light-mid (disabled)
400:  mid-light
500:  base color
600:  mid-dark
700:  dark (text)
800:  darker (heading)
900:  darkest (high contrast)
```

Tailwind / Material approach.

## Semantic tokens (modern systems)

Instead of `color: #FF6B35`, use:
```
--color-brand-primary
--color-text-primary
--color-text-secondary
--color-bg-surface
--color-border-default
--color-state-error
```

Allows dark mode + theming without rewrites.

## Anti-patterns

- ❌ Picking colors from inspiration without testing contrast
- ❌ Pure black (#000) for body text (too harsh — use #1A1A1A)
- ❌ Pure white (#FFF) for everything (use off-white for warmth)
- ❌ More than 7 distinct hues
- ❌ Inconsistent saturation across palette
- ❌ Color tokens that hardcode meaning (`--color-red` instead of `--color-error`)

## Output format

```markdown
## Palette — <brand>

### Concept
<3 mood words>

### Production palette (10 colors)
| Token | Hex | Role | Contrast on white | Contrast on dark |
|---|---|---|---|---|
| Brand Primary | #FF6B35 | hero | 3.6 | 5.4 |
| ... | | | | |

### Semantic tokens
<list>

### Tonal scales
<10-shade scale per primary>

### Dark mode mapping
<light → dark variant>

### Accessibility report
- All text pairs: ✓ AA pass
- Issue: <if any>
```

## Integration
- `brand-identity-designer` for system
- `ui-ux-pro-max` for digital application
- `accessibility-auditor` for validation
