Decoded design system

Todoist's decoded design system: background #FEFDFC, text #25221E, accent #E34432, link #0F66AE, primary #E34432; type scale h1 55px / h2 38px / body 15.5px; 4px spacing base; 8px base radius. The single interactive/action color is #E34432 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FEFDFC`
surface	`#F0EFEE`
border	`#DDDCDA`
text	`#25221E`
text_muted	`#777572`
primary	`#E34432`
accent	`#E34432`
link	`#0F66AE`
secondary	`#DFAB47`
button_bg	`#E34432`
button_text	`#FFFFFF`

Using these colors

Action color #E34432 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #E34432 — one role, not several (the action color).
accent #E34432 — 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 #0F66AE — inline text links and link-styled controls.
secondary #DFAB47 — 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.
