# Shortwave — Design System

> dark, modern, medium, custom

Shortwave automates email in round geometry: Poppins at 64px/400 white on deep space, 16-18px body, and flat text CTAs. AI-agent chat panels and inbox screenshots do the demonstrating while gradient auroras keep the dark canvas alive — the Google-alumni email client that pitches AI triage with a friendly, circular voice.

## Colors

| Role | Value |
|------|-------|
| bg | `#0F0F16` |
| surface | `#1C1C22` |
| border | `#303036` |
| text | `#ECECEE` |
| text_muted | `#98989B` |
| primary | `#356AFF` |
| accent | `#356AFF` |
| link | `#9E9EFF` |
| secondary | `#6593FF` |
| button_bg | `#356AFF` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#356AFF` — 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 `#356AFF` — one role, not several (your action color).
- **accent** `#356AFF` — 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** `#9E9EFF` — inline text links and link-styled controls.
- **secondary** `#6593FF` — 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.
