# Design System — MDCalc

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

## Ground
- **Light ground** (#FFFFFF), from MDCalc's site background #FFFFFF. Pages and panels sit on it.
- Main text: #032A25 (15.42:1 on the ground).
- Secondary text is #032A25 at 88% / 76% / 60%; hairlines and plate borders #032A25 at 16%.

## Color
- **Accent on the ground: #117A66** (5.25:1). Use it for kickers, key numbers and one highlight per screen, not for large fills.
- **Primary #117A66** for filled shapes (buttons, chips, bars), with #FFFFFF text on it (5.25:1).
- Quote every hex exactly as written above.

## Type
- Headlines: **Archivo**. Body: **IBM Plex Sans**. Both on Google Fonts.
- MDCalc's site uses Facit / IBM Plex Sans; these are the closest free look-alikes.

## Shape
- Cards and panels: 4px corners. Buttons and chips: 8px.

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