Decoded design system

Whoop's decoded design system: background #000000, text #ECECEE, accent #4A53FF, link #FF0026, primary #4A53FF; type scale h1 120px / h2 100px / body 20px; 4px spacing base; 15px base radius. The single interactive/action color is #4A53FF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#000000`
surface	`#0E0E0E`
border	`#232323`
text	`#ECECEE`
text_muted	`#929293`
primary	`#4A53FF`
accent	`#4A53FF`
link	`#FF0026`
secondary	`#41FF31`
button_bg	`#4A53FF`
button_text	`#FFFFFF`

Using these colors

Action color #4A53FF — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #4A53FF — one role, not several (the action color).
accent #4A53FF — 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 #FF0026 — inline text links and link-styled controls.
secondary #41FF31 — 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.
