Decoded design system

Chroma's decoded design system: background #FAFAF9, text #0A0A0A, accent #171717, link #4A5565, primary #364153; type scale h1 24px / h2 16px / body 12px; 8px spacing base; 0px base radius. The single interactive/action color is #171717 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FAFAF9`
surface	`#EBEBEA`
border	`#D6D6D5`
text	`#0A0A0A`
text_muted	`#656564`
primary	`#364153`
accent	`#171717`
link	`#4A5565`
secondary	`#101828`
button_bg	`#171717`
button_text	`#FAFAFA`

Using these colors

Action color #171717 — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #171717 — one role, not several (the action color).
accent #171717 — 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.
primary #364153 — a brand color — but the call-to-action uses #171717, not this.
link #4A5565 — inline text links and link-styled controls.
secondary #101828 — 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.
