# Design System — Happy Billing

> Read from Happy Billing's public website (happybilling.co) by Clinical Terminal. Not reviewed by Happy Billing.
> Use it as inspiration: borrow the ideas, not Happy Billing's name, logo or identity.

## Ground
- **Light ground** (#FFFFFF), from Happy Billing's site background #FFFFFF. Pages and panels sit on it.
- Main text: #070707 (20.14:1 on the ground).
- Secondary text is #070707 at 88% / 76% / 60%; hairlines and plate borders #070707 at 16%.

## Color
- **Accent on the ground: #00634C** (7.27:1). Use it for kickers, key numbers and one highlight per screen, not for large fills.
- **Primary #00634C** for filled shapes (buttons, chips, bars), with #FFFFFF text on it (7.27:1).
- Secondary accent #1E87F0: charts and a second data series only.
- Quote every hex exactly as written above.

## Type
- Headlines: **Inter**. Body: **Inter**. Both on Google Fonts.

## Shape
- Cards and panels: 6px corners. Buttons and chips: 6px.

## Voice
- Tone: professional. Energy: low. Written for patients and healthcare professionals.
- Headlines are short and concrete.
