Color System Layers

1. Brand Palette

Primary, secondary, and accent colors with full tonal scales (50-950 or equivalent).

2. Neutral Palette

Gray scale for text, backgrounds, borders, and surfaces.

3. Semantic Colors

Success (green), warning (amber), error (red), info (blue)

Each with background, foreground, border, and icon variants

4. Extended Palette

Accessibility Requirements
