### What is the Gamma DESIGN.md?

A plain-text file with Gamma’s measured colors, type, spacing, corners and components as tokens, plus short rules, in the DESIGN.md format Google published with Stitch. Your AI coding agent reads it and builds in this style. More about DESIGN.md.

### How do I use it with Claude Code or Cursor?

Download the file and put it in your project’s root folder, then ask your agent to follow DESIGN.md. Step-by-step guides: Claude Code, Cursor, Codex, GitHub Copilot.

### Is this Gamma’s official design system?

No. Sitepeel measured it from gamma.app’s public page on November 4, 2026. It is an independent analysis, not made or approved by Gamma.

### Can I use Gamma’s style in my own product?

Use it to learn, prototype and compare. For a real product, make the style your own, and never copy Gamma’s logo, name, pictures or text.

### How accurate are the values?

Each value was measured on the rendered page after it fully loaded, on desktop and mobile: colors where they appear, type with tracking, spacing, corners, shadows and hover states. Sites change, so check the date at the top.

# Gamma Design System

## Overview

Gamma describes itself as: “Design stunning presentations, websites, and more with Gamma—your all-in-one AI-powered design partner. No code or design experience needed.” The interface is light, built on **White (#FFFFFF)** with **Slate (#66666B)** text, and **Dark Blue (#0540AD)** as the main accent.

Type is set in **ESBuild** and **PPMori**. Headlines run large with tight negative tracking; body text is 18px. Depth comes from soft drop shadows. Controls are pill-shaped.

Measured from [gamma.app](https://gamma.app/) on November 4, 2026 at 1440×900 and 390×844 from 341 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 8 roles, plus gradient stops #D0E6FE.

- **White (#FFFFFF):** Page background, seen 7 times. Token `background`, CSS `--chakra-colors-white`.
- **Slate (#66666B):** Primary text and headings, seen 26 times. Token `on-surface`, CSS `--chakra-colors-gray-600`.
- **White 80% (#FFFFFFCC):** Translucent fill for cards and controls, seen 4 times. Token `overlay`.
- **Pale Blue (#D0E6FE):** Borders and dividers, seen 4 times. Token `outline`.
- **Dark Blue (#0540AD):** Primary buttons and calls to action, seen 18 times. Token `primary`, CSS `--chakra-colors-blue-800`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Deep Blue (#002253):** Accent on large areas, seen 54 times. Token `secondary`.
- **Vivid Blue (#0740DF):** Accent in text, fills and borders, seen 10 times. Token `tertiary`.

## Typography

**ESBuild** and **PPMori** share the interface. Fallback stack: `ESBuild, sans-serif`.

- **headline-display:** ESBuild 72px at weight 600, line height 1, tracking -0.025em (48px on mobile). Page title (h1).
- **headline-lg:** ESBuild 48px at weight 500, line height 1, tracking -0.02em. Section headings (h2).
- **headline-md:** PPMori 30px at weight 700, line height 1.1, tracking -0.02em. Sub-section headings.
- **headline-sm:** PPMori 24px at weight 500, line height 1.5. Card and feature titles.
- **title-lg:** PPMori 20px at weight 600, line height 1.1, tracking -0.02em. Small titles.
- **body-md:** PPMori 18px at weight 600, line height 1.2. Body text.
- **label-md:** PPMori 16px at weight 500, line height 1.5. Buttons, navigation and labels.
- **label-sm:** PPMori 14px at weight 500, line height 1.5. Small labels and badges.

## Layout

Spacing follows a 4px grid: 97% of measured gaps and paddings are multiples of 4px.

- **Scale:** sm 8px, md 12px, lg 24px, xl 48px.
- **Sections:** 96px vertical padding between major sections.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Breakpoints:** 400px, 425px, 426px, 550px, 600px, 640px, 767px, 768px, 896px.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(0, 0, 0, 0.1) 0px 20px 25px -5px, rgba(0, 0, 0, 0.04) 0px 10px 10px -5px`
- `rgba(255, 255, 255, 0.48) 0px 2px 4px 0px`
- `rgba(0, 34, 83, 0.15) 0px 2px 8px 0px`

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **sm (6px):** 192 elements.
- **full (9999px):** 100 elements.
- **md (24px):** 56 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Start for free”):** #0540AD fill, #FFFFFF text, 16px/500, 24px radius, padding 0px 32px.
- **button-primary-hover:** background #0B2E79, text #FFFFFF on hover.
- **button-outline (“Start for free”):** #FFFFFF fill, #002253 text, 18px/600, 9999px radius, padding 0px 32px, border 1px solid #D0E6FE, shadow `rgba(255, 255, 255, 0.48) 0px 2px 4px 0px`.
- **button-outline-hover:** background #EBF3FE, text #002253 on hover.
- **button-ghost (“Products”):** transparent fill, #FFFFFFCC text, 16px/500, 24px radius, padding 0px 16px.
- **link:** transparent fill, #FAF9F5 text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page.
- Do reserve #0540AD for primary actions and key highlights.
- Do set headlines in ESBuild with tight tracking (-0.025em).
- Do keep spacing on the 4px grid.
- Do make buttons and chips fully rounded (9999px); most other elements use 6px corners.
- Don't introduce new font families beyond ESBuild and PPMori.
- Don't use #0540AD for large backgrounds or body text.
- Don't make interface transitions slower than 0.2s.

## Motion

Interface transitions are quick: 0.2s, 0.15s. Longer ambient animations run 0.9s.

- **Easing:** `ease`, `cubic-bezier(0.22, 1, 0.36, 1)`, `cubic-bezier(0, 0, 0.2, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
