Decoded design system

Weights & Biases's decoded design system: background #1A1C1F, text #ECECEE, accent #FCBC32, link #FCBC32, primary #00AFC2; type scale h1 72px / h2 38px / body 20px; 4px spacing base; 4px base radius. The single interactive/action color is #1A1C1F — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#1A1C1F`
surface	`#26282B`
border	`#393B3E`
text	`#ECECEE`
text_muted	`#9C9C9F`
primary	`#00AFC2`
accent	`#FCBC32`
link	`#FCBC32`
secondary	`#FFCC33`
button_bg	`#1A1C1F`
button_text	`#FFFFFF`

Using these colors

Action color #1A1C1F — the single interactive color; only on things you click or must notice, never large fills.
accent, link are all #FCBC32 — one role, not several (the action color).
accent #FCBC32 — accent for emphasis — keep it rare on the page.
primary #00AFC2 — a brand color — but the call-to-action uses #1A1C1F, not this.
secondary #FFCC33 — 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.
