Decoded design system

Colophon's decoded design system: background #F8F8F8, text #000000, accent #FFEE3B, link #FFEE3B, primary #FFEE3B; type scale h1 24px / h2 24px / body 24px; 5px spacing base; 0px base radius. The single interactive/action color is #000000 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#F8F8F8`
surface	`#E9E9E9`
border	`#D2D2D2`
text	`#000000`
text_muted	`#5E5E5E`
primary	`#FFEE3B`
accent	`#FFEE3B`
link	`#FFEE3B`
button_bg	`#000000`
button_text	`#FFFFFF`

Using these colors

Action color #000000 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link are all #FFEE3B — one role, not several (the action color).
accent #FFEE3B — accent for emphasis — keep it rare on the page.
