Dark Mode Implementation — Tokens, Images & Testing
Tokens make it trivial — or impossible
Semantic tokens (surface, on-surface, muted) flip themes with one attribute change; hardcoded hexes make dark mode a rewrite. If the token architecture from our design-system guide exists, implementation is days. Without it, weeks.
Beyond color inversion
Pure-black backgrounds strain eyes; dark grays (#121212 family) with elevated surfaces read better. Images need dimming strategies, logos need theme variants, and shadows become glows. Test brand accents at both themes — some hues vibrate painfully on dark.
Contrast and persistence
WCAG AA contrast (4.5:1 body text) applies equally in dark; automated checks run per theme in CI. Persist user choice (light/dark/system) in localStorage with system-preference default — and respect it before first paint to avoid theme flash.
