Dark Mode tips

🌙

Pure white (#ffffff) on pure black (#000000) gives 21:1 — too harsh. Slate-200 (#e2e8f0) on slate-900 (#0f172a) gives 13.1:1, easier on the eyes and still AAA compliant.

💡

Common dark mode mistake: gray-on-gray. Light gray text on dark gray background looks "stylish" but often fails AA (try #94a3b8 on #1e293b — only 4.1:1).

🎯

Accent colors that work on light backgrounds often fail on dark. Test brand accents against your dark surface color before shipping.
