Decoded design system

Clerk's decoded design system: background #F7F7F8, text #131316, accent #6C47FF, link #6C47FF, primary #747686; type scale h1 64px / h2 32px / body 13px; 4px spacing base; 0px base radius. The single interactive/action color is #6C47FF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#F7F7F8`
surface	`#E9E9EA`
border	`#D4D4D6`
text	`#131316`
text_muted	`#69696B`
primary	`#747686`
accent	`#6C47FF`
link	`#6C47FF`
secondary	`#5E5F6E`
button_bg	`#6C47FF`
button_text	`#FFFFFF`

Using these colors

Action color #6C47FF — the single interactive color; only on things you click or must notice, never large fills.
accent, link, button_bg are all #6C47FF — one role, not several (the action color).
accent #6C47FF — 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 #747686 — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #6C47FF).
secondary #5E5F6E — 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.
