Midnight UI

A ready-made dark-mode starter: three slate surfaces, one violet accent, one near-white text tone. The surface steps are close enough to layer cards without hard borders.

Accessibility snapshot

Each color's WCAG contrast ratio against white and black text — AA means it can carry normal-size text (≥4.5:1) on that background. Test your exact pairings in the contrast checker.

Color blindness safety

Every pair in this palette (10 pairs) checked with CIEDE2000 under normal vision plus the four strongest color vision deficiency types. A pair is flagged when it drops below ΔE 10 — the zone where colors get hard to tell apart at a glance.

#020618 vs #1d293d Achromatopsia ΔE 9.1 Hard to distinguish

#020618 vs #1d293d Protanopia ΔE 9.6 Hard to distinguish

#020618 vs #1d293d Deuteranopia ΔE 9.7 Hard to distinguish

#020618 vs #1d293d Normal vision ΔE 9.8 Hard to distinguish

Swatches show the pair as that viewer would see it. Flagged pairs are fine decoratively — just don’t make them the only difference between two states. Explore any pair in the simulator.

In a real interface

Roles assigned by lightness: the lightest color as background, the darkest as text, the first two palette colors as primary and accent.
