Linear — Design System

dark · modern · medium · custom · confidence 92%

Linear is near-black restraint with one decisive accent. The canvas sits at #08090A and a single indigo (#5E6AD2) does all the pointing; everything else is a disciplined grayscale ladder. Inter carries every word — no display face, no flourish — set tight on a strict 8px rhythm so the interface reads as engineered, not decorated. Corners are minimal (2px on surfaces, fully-rounded pills on primary buttons), borders are hairline #26282A, and shadows are nearly absent — depth comes from luminance, not drop-shadow. It feels fast before you click: quiet, dense, keyboard-first, and unmistakably built for people who ship.

# Linear — Design System

> dark, modern, medium, custom

Linear is near-black restraint with one decisive accent. The canvas sits at #08090A and a single indigo (#5E6AD2) does all the pointing; everything else is a disciplined grayscale ladder. Inter carries every word — no display face, no flourish — set tight on a strict 8px rhythm so the interface reads as engineered, not decorated. Corners are minimal (2px on surfaces, fully-rounded pills on primary buttons), borders are hairline #26282A, and shadows are nearly absent — depth comes from luminance, not drop-shadow. It feels fast before you click: quiet, dense, keyboard-first, and unmistakably built for people who ship.

## Colors

| Role | Value |
|------|-------|
| bg | `#08090A` |
| surface | `#141516` |
| border | `#26272A` |
| text | `#D0D6E0` |
| text_muted | `#84888E` |
| primary | `#D0D6E0` |
| accent | `#E5E5E6` |
| link | `#5E6AD2` |
| secondary | `#E4F222` |
| button_bg | `#E5E5E6` |
| button_text | `#08090A` |

**Using these colors**

- **Action color** `#E5E5E6` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#E5E5E6` — one role, not several (your action color).
- **accent** `#E5E5E6` — 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.
- **primary** `#D0D6E0` — ≈ the text color — a foreground/text color, not an action color (action = #E5E5E6).
- **link** `#5E6AD2` — inline text links and link-styled controls.
- **secondary** `#E4F222` — 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.

## Typography

- Heading: **SF Pro Display** _(free fallback: Inter)_
