Dark Mode Design Best Practices

⏱️ 20 min
🌙 Dark Mode

More Than Just Inverted Colors

Dark mode is more than inverting colors. Elevation, glow effects, color saturation adjustments, and accessibility.

Elevation, Saturation, Accessibility

🏔️
Elevation via Lightness
In dark UI, surfaces closer to the "top" get lighter (not shadowed), since shadows barely read on dark backgrounds.
✨
Glow Over Shadow
Subtle light glows communicate elevation and focus where drop shadows would disappear.
🎚️
Desaturate Accent Colors
Fully saturated bright colors vibrate uncomfortably against dark backgrounds — dark mode palettes typically reduce saturation.
♿
Contrast Still Applies
WCAG contrast ratios apply in dark mode exactly as in light mode — pure white on pure black can even cause halation for some users.

Common Dark Mode Mistakes

  • Simply inverting a light-mode palette instead of designing dedicated dark surfaces and text colors.
  • Using pure black (#000000) backgrounds, which can cause visual smearing on OLED screens during motion.
  • Forgetting to re-check contrast ratios after switching themes.
