Tokens

Cartesia's decoded design system: background #F9F9F8, text #1E1C1A, accent #004E23, link #004E23, primary #004E23; type scale h1 36px / h2 24px / body 48px; 4px spacing base; 4px base radius. The single interactive/action color is #004E23 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#F9F9F8`
surface	`#EBEBEA`
border	`#D8D7D6`
text	`#1E1C1A`
text_muted	`#716F6E`
primary	`#004E23`
accent	`#004E23`
link	`#004E23`
button_bg	`#004E23`
button_text	`#FEFEFE`

Using these colors

Action color #004E23 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #004E23 — one role, not several (the action color).
accent #004E23 — 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.

- **Action color** `#004E23` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `link`, `button_bg` are all `#004E23` — one role, not several (your action color).
- **accent** `#004E23` — 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.
