概要

Dark mode design is the practice of creating interfaces with dark backgrounds and light text. Not just inverting colors, true dark mode requires new contrast ratios, adjusted shadows (inverted), custom color palettes, and careful attention to readability. Designers skilled in dark mode earn 5-10% premium because they ship products that please users and pass WCAG accessibility audits. Learning: 3-4 weeks (visual + technical knowledge).

Dark Mode Designとは

Dark mode design is the creation of interfaces with dark backgrounds (charcoal, near-black) and light text (off-white, light gray). Beyond simple color inversion, true dark mode requires redesigned shadows, adjusted transparency, rebalanced accent colors, and careful contrast management to meet accessibility standards. Example: GitHub dark mode (GitHub-dark theme), Twitter dark mode, Apple iOS dark mode. Each handles text, shadows, and accents differently from light mode.

❓ よくある質問

Should I just invert the light mode colors?

No. Inverting creates poor contrast and looks harsh. Design dark mode independently: use desaturated, raised-value backgrounds (dark grays, not black). Keep text light but not pure white. Use muted accent colors.

What contrast ratio do I need for dark mode?

Same as light mode: WCAG AA = 4.5:1 (normal text), 3:1 (large text). WCAG AAA = 7:1. Measure with tools like WebAIM Contrast Checker.

How do I handle shadows in dark mode?

Light mode shadows are darker (darken the background). Dark mode shadows are lighter (use white with opacity). Shadows become visible by being lighter than background, not darker.

Can users toggle dark mode on a per-page basis?

Yes, but don't. Toggle at OS level (device dark mode) or site level (one toggle for whole site). Per-page dark mode is confusing navigation.

How do I test dark mode accessibility?

Use WCAG contrast checker on each text color. Use color blindness simulator (protanopia, deuteranopia, tritanopia). Test on AMOLED displays (pure black background). Ask users with vision disabilities.
