# Void - Palette Reference

Every brand color in four color spaces plus usage and contrast notes. HEX is
canonical. RGB / HSL / OKLCH are computed conversions (sRGB, D65) for tooling
and perceptual work. Source of truth: `frontend/app/styles/tokens.css`.

Two editions:
- **Morning Edition (light)** - warm newsprint, aged broadsheet under morning light.
- **Evening Edition (dark)** - walnut broadsheet, not terminal black.

## 1. Brand Accents

One accent per product. Accents are **decorative marks** (large logo use) and
are not bound by the WCAG AA 4.5:1 small-text rule. For small bold labels on
paper, use the `-ink` shade.

## 2. Bias Spectrum

The earned colors. Blue (left) -> **Green (center ONLY)** -> Red (right). Depth
encodes distance from center: the far extremes are deepest. Never recolor these
for decoration. Light values are AA on paper; dark values are AA-retuned for
walnut.
