Tokens

Cognition's decoded design system: background #F7F6F5, text #000000, accent #FF0000, link #FF0000, primary #2200FF; type scale h1 36px / h2 20px / body 10px; 4px spacing base; 0px base radius. The single interactive/action color is #191919 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#F7F6F5`
surface	`#E8E7E6`
border	`#D1D1D0`
text	`#000000`
text_muted	`#5D5D5D`
primary	`#2200FF`
accent	`#FF0000`
link	`#FF0000`
button_bg	`#191919`
button_text	`#F7F6F5`

Using these colors

Action color #191919 — the single interactive color; only on things you click or must notice, never large fills.
accent, link are all #FF0000 — one role, not several (the action color).
accent #FF0000 — accent for emphasis — keep it rare on the page.
primary #2200FF — a brand color — but the call-to-action uses #191919, not this.
