# Synthesia — Design System

> light, modern, medium, custom

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F2F3F4` |
| border | `#E0E1E5` |
| text | `#333B52` |
| text_muted | `#808593` |
| primary | `#3E57DA` |
| accent | `#3E57DA` |
| link | `#333B52` |
| secondary | `#0D0F2C` |
| button_bg | `#3E57DA` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#3E57DA` — 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 `#3E57DA` — one role, not several (your action color).
- **accent** `#3E57DA` — 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** `#333B52` — inline text links and link-styled controls.
- **secondary** `#0D0F2C` — 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.
