3.32.1Definition & Anatomy

Dark mode is an alternate color scheme optimized for low-light viewing and reduced eye strain, built as a genuine parallel palette rather than a naive color inversion of the light theme.

3.32.2Common Mistakes

  • Simple CSS color inversion, which breaks images, shadows, and brand colors that weren't designed to invert.
  • Insufficient contrast in dark mode specifically, since perceived contrast behaves differently on dark backgrounds.

3.32.3Best Practices

  • Design dark mode as its own considered palette, not an automatic inversion of light-mode values.
  • Respect the operating system's light/dark preference by default, with a manual override available.
ExampleApple's Human Interface Guidelines specify true dark-mode-specific color tokens rather than inverted light-mode colors, since pure black backgrounds and inverted shadows behave visually differently than a naive inversion would produce.
