Tokens

Biome's decoded design system: background #FFFFFF, text #0A0A0B, accent #0065DA, link #0065DA, primary #0065DA; type scale h1 64px / h2 20px / body 16px; 4px spacing base; 3px base radius. The single interactive/action color is #0065DA — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0065DA — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #0065DA — one role, not several (the action color).
• accent #0065DA — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
• secondary #ABB2BF — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
