# Missive — Design System

> light, modern, medium, custom

Missive dresses team email in editorial serif: Tiempos Headline at 56px/400 in soft ink #34363A, Inter at 18-20px for the workflow copy, quiet 8px-radius buttons. Shared-inbox UI in warm neutrals does the demonstrating — the serif signals that email is writing, and writing deserves a newspaper face.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F2F2F3` |
| border | `#E0E0E1` |
| text | `#34363A` |
| text_muted | `#818284` |
| primary | `#2266ED` |
| accent | `#2266ED` |
| link | `#3898EC` |
| secondary | `#0082F3` |
| button_bg | `#2266ED` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#2266ED` — 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 `#2266ED` — one role, not several (your action color).
- **accent** `#2266ED` — 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** `#3898EC` — inline text links and link-styled controls.
- **secondary** `#0082F3` — 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.
