Todoist — decoded design system
Todoist's design system, decoded live by Mozaika: measured color roles, type scale, buttons with real hover/focus states, motion and the brand's own tokens.
This is a static, crawlable rendering for search & AI engines. The interactive version — filters, live decode console, copy & export — is at https://mozaika.design/decode/todoist.com.
Decoded design system
Todoist's decoded design system: background #FEFDFC, text #25221E, accent #E34432, link #0F66AE, primary #E34432; type scale h1 55px / h2 44px / body 21px; 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_bgare 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.
