Decoded design system

Builder.io's decoded design system: background #0A0A0A, text #FAF9F5, accent #01C8F1, link #4ADE80, primary #01C8F1; type scale h1 56px / h2 46px / body 16px; 4px spacing base; 4px base radius. The single interactive/action color is #01C8F1 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#0A0A0A`
surface	`#181818`
border	`#2E2D2D`
text	`#FAF9F5`
text_muted	`#9E9E9B`
primary	`#01C8F1`
accent	`#01C8F1`
link	`#4ADE80`
secondary	`#BEF0F5`
button_bg	`#01C8F1`
button_text	`#0A0A0A`

Using these colors

Action color #01C8F1 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #01C8F1 — one role, not several (the action color).
accent #01C8F1 — 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 #4ADE80 — inline text links and link-styled controls.
secondary #BEF0F5 — 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.
