Todoist — Design System

light · modern · medium · custom · confidence 92% · deep decode

Todoist is warm pragmatism: Graphik at 55px/600 in coffee-dark #25221E on paper #FEFDFC, generous 20px body text, and its signature red saved for the app UI rather than the page chrome. Handwritten-style annotations and device frames keep the tone personal — twenty years of to-do lists distilled into typography that feels like a well-kept notebook.

Tokens

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

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.

# Todoist — Design System

> light, modern, medium, custom — deep decode (measured live)

Todoist is warm pragmatism: Graphik at 55px/600 in coffee-dark #25221E on paper #FEFDFC, generous 20px body text, and its signature red saved for the app UI rather than the page chrome. Handwritten-style annotations and device frames keep the tone personal — twenty years of to-do lists distilled into typography that feels like a well-kept notebook.

## Colors

| 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; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `button_bg` are all `#E34432` — one role, not several (your 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.
- **Page coverage** (full-page screenshot pixels): `#FEFDFC` 90.8% · `#D7C0BA` 9.2%

## Typography

- Heading: **Graphik** _(free fallback: Inter)_
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 55px / 600 · lh 63px · tracking -0.55px |
| h2 | 44px / 600 · lh 51px · tracking -0.44px |
| h3 | 38px / 700 · lh 49px · tracking -0.19px |
| body | 21px / 475 · lh 33px |
| small | 19px / 600 · lh 26px · tracking 0.18px |

- Weight ladder: 400 · 475 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Graphik is proprietary — closest free match: Inter (Google). Load Inter; keep Graphik first so licensed users still get it. Inter — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 7px, 8px, 9px, 10px, 12px, 14px, 16px, 20px — snap all gaps/padding to these
- section rhythm: 48px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 15px
- card: 10px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#E34432` / `#FFFFFF` | none | 8px | 9px 14px 9px 14px | 600 15.5px / 0.155px | none |
| secondary | `#4A4744` / `#FFFFFF` | none | 15px | — | — | none |

**States (measured, not guessed)**

- primary hover: background `#CF3520`
- primary focus: box-shadow `rgb(225, 240, 244) 0px 0px 0px 4px, rgb(41, 122, 188) 0px 0px 0px 1px`
- transition: `transform 0.15s cubic-bezier(0.2, 0.8, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(37, 34, 30, 0.04) 0px 1px 0px 0px`
- card: `rgba(37, 34, 30, 0.07) 0px 14px 19px -9px, rgba(37, 34, 30, 0.18) 0px 10px 48px 0px`
- overlay: `rgba(0, 0, 0, 0.18) 0px 12px 32px 0px`

## Motion
- durations: 150ms (dominant) · 200ms · 300ms
- easings: `cubic-bezier(0.2, 0.8, 0.2, 1)` (dominant) · `ease-out`
- animated properties: transform, background-color, opacity, color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Their own tokens (verbatim from :root)

| Token | Value |
|-------|-------|
| `--osano-clear-dialog-background` | `rgba(255,255,255,0)` |
| `--osano-button-border-color` | `#e44232` |

_…and 108 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1360px
- nav: 72px

## Motion choreography (measured)
Load order: `div.scroller` @0ms → `div.osano-cm-info-dialog__in` @307ms → `div.osano-cm-window__dialog` @351ms → `button.osano-cm-dialog__close` @351ms → `button.osano-cm-dialog__close` @351ms → `button.osano-cm-dialog__close` @351ms
- `div.scroller` — transform translate(0%)→translate(calc(-33.3333% - 10.6667px)) — 30000ms · loops
- scroll reveal: 3 elements rest at opacity 0, animate in over 0.3s ease-in-out (1 revealed during the drive).
- overlay dialog (auto-opened): panel #FFFFFF · r 12px · border 1px solid rgba(37, 34, 30, 0.12) · shadow rgba(0, 0, 0, 0.18) 0px 12px 32px 0px

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #CF3520 · underline

## Responsive (measured)
- breakpoints: 480px · 768px · 960px · 1120px · 1200px
- mobile (390px): hero 37px · body 16px · nav: hamburger

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
