Tokens

AssemblyAI's decoded design system: background #FDFCF8, text #1D1B16, accent #3923C7, link #C7C3B2, primary #3923C7; type scale h1 72px / h2 64px / body 12px; 4px spacing base; 0px base radius. The single interactive/action color is #3923C7 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FDFCF8`
surface	`#EFEEEA`
border	`#DBDAD6`
text	`#1D1B16`
text_muted	`#72706B`
primary	`#3923C7`
accent	`#3923C7`
link	`#C7C3B2`
button_bg	`#3923C7`
button_text	`#FFFFFF`

Using these colors

Action color #3923C7 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #3923C7 — one role, not several (the action color).
accent #3923C7 — 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.
link #C7C3B2 — fails contrast on the background (~1.7:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
