Dark Mode Best Practices: More Than Inverting Colors

Dark mode is one of the most-requested features and most-commonly-botched implementations. Inverting the palette produces a flat, painful UI.

Start Dark Gray

Pure black causes eye strain on OLED. Use #121212 baseline. Reserve black for specific effects.

Elevation Via Lightness

Shadows do not work in dark mode. Higher surfaces get lighter. Material Design's dark theme is the pattern.

Desaturate, Do Not Invert

Vibrant brand on white looks toxic on dark gray. Keep both color tokens in your design system.

Test Contrast Both Modes

4.5:1 text. Easy to fail in dark mode. See accessibility.
