Udio composes on black: Innovator Grotesk at 60px/400 ('Make your music'), zero-radius ghost buttons, and album-art tiles from generated tracks supplying the color. Waveforms and play controls turn the page into a listening surface — an AI music studio whose restrained grotesk lets the audio-first content feel like a label catalog.

# Udio — Design System

> dark, modern, high, custom

Udio composes on black: Innovator Grotesk at 60px/400 ('Make your music'), zero-radius ghost buttons, and album-art tiles from generated tracks supplying the color. Waveforms and play controls turn the page into a listening surface — an AI music studio whose restrained grotesk lets the audio-first content feel like a label catalog.

## Colors

| Role | Value |
|------|-------|
| bg | `#000000` |
| surface | `#0E0E0E` |
| border | `#232323` |
| text | `#ECECEE` |
| text_muted | `#929293` |
| primary | `#211630` |
| accent | `#E30B5D` |
| link | `#E30B5D` |
| secondary | `#4A5565` |

**Using these colors**

- **Action color** `#E30B5D` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link` are all `#E30B5D` — one role, not several (your action color).
- **accent** `#E30B5D` — 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** `#211630` — a brand color — but the call-to-action uses #E30B5D, not this.
- **secondary** `#4A5565` — 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: **Inter**
- Body: **Inter**
