Decoded design system

On Running's decoded design system: background #FFFFFF, text #000000, accent #2F7EFE, link #2F7EFE, primary #ED0000; type scale h1 32.96px / h2 52.992px / body 32.96px; 4px spacing base; 4px base radius. The single interactive/action color is #FFFFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#EFEFEF`
border	`#D8D8D8`
text	`#000000`
text_muted	`#606060`
primary	`#ED0000`
accent	`#2F7EFE`
link	`#2F7EFE`
secondary	`#0000EE`
button_bg	`#FFFFFF`
button_text	`#000000`

Using these colors

Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
accent, link are all #2F7EFE — one role, not several (the action color).
accent #2F7EFE — accent for emphasis — keep it rare on the page.
primary #ED0000 — a brand color — but the call-to-action uses #FFFFFF, not this.
secondary #0000EE — 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.
