### What is the Homebrew design system?

The design system on this page is brew.sh’s, as measured on November 4, 2026: #E2A843 as the main color and 6.4px corners, written down as a DESIGN.md. It is not Homebrew’s own documentation.

### What is Homebrew built with?

Homebrew’s website (brew.sh) is built with Jekyll, Preact, Fastly and GitHub Pages. Measured on November 4, 2026.

### What is the Homebrew DESIGN.md?

A plain-text file with Homebrew’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 Homebrew’s official design system?

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

### Can I use Homebrew’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 Homebrew’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.

# Homebrew Design System

## Overview

Homebrew describes itself as: “The Package Manager for Everywhere.” The interface is dark, built on **Warm Graphite (#2E2A24)** with **White (#FFFFFF)** text, and **Orange (#E2A843)** as the main accent.

Type is set in **system-ui**. Headlines run large; body text is 16px. The surface language is flat. Corners are mostly 6.4px.

Measured from [brew.sh](https://brew.sh/) on November 4, 2026 at 1440×900 and 390×844 from 196 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 13 roles.

- **Warm Graphite (#2E2A24):** Page background, seen 1 time. Token `background`, CSS `--docsearch-footer-background`.
- **White (#FFFFFF):** Primary text and headings, seen 26 times. Token `on-surface`, CSS `--docsearch-hit-active-color`.
- **Gray (#999999):** Secondary text, seen 8 times. Token `on-surface-variant`.
- **White 6% (#FFFFFF0F):** Translucent fill for cards and controls, seen 7 times. Token `overlay`.
- **Near Black 30% (#0000004D):** Stronger translucent fill, seen 1 time. Token `overlay-strong`, CSS `--docsearch-hit-background`.
- **Dark Orange 30% (#A26B144D):** Borders and dividers, seen 7 times. Token `outline`.
- **Dark Orange (#745626):** Secondary dividers, seen 1 time. Token `outline-variant`.
- **Orange (#E2A843):** Brand accent (CSS variable), seen 49 times. Token `primary`, CSS `--docsearch-primary-color`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.
- **Mist (#EBEDF0):** High-contrast fills, seen 1 time. Token `inverse-surface`, CSS `--docsearch-searchbox-background`.
- **Orange (#9C7645):** Accent in text, fills and borders, seen 22 times. Token `secondary`.
- **Dark Cyan (#008080):** Accent in text, fills and borders, seen 14 times. Token `tertiary`.
- **Light Orange (#FFD79A):** Warnings and highlights, seen 25 times. Token `warning`.

## Typography

**system-ui** carries the whole interface. Fallback stack: `ui-sans-serif, -apple-system, BlinkMacSystemFont, Helvetica Neue`.

- **headline-display:** system-ui 53px at weight 900, line height 0.95 (29px on mobile). Page title (h1).
- **headline-lg:** system-ui 48px at weight 800, line height 1.1 (24px on mobile). Section headings (h2).
- **headline-md:** system-ui 20px at weight 800, line height 1.1. Sub-section headings.
- **body-md:** system-ui 16px at weight 400, line height 1.48. Body text.
- **body-lg:** system-ui 18px at weight 700, line height 1.48. Lead paragraphs.
- **body-sm:** system-ui 13px at weight 400, line height 1.48. Secondary and small text.
- **label-md:** system-ui 16px at weight 700, line height 1.48. Buttons, navigation and labels.
- **label-sm:** system-ui 13px at weight 700, line height 1.48. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 50% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** sm 5.6px, md 16px, lg 20px, xl 35.2px.
- **Gaps:** 19.2px is the most common gap in flex and grid layouts.
- **Breakpoints:** 480px, 700px, 768px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from color contrast and #A26B144D borders.

## Shapes

Most elements use 6.4px corners. Measured radii, most used first:

- **md (6.4px):** 30 elements.
- **sm (4px):** 4 elements.

## Components

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

- **button-primary (“Search K”):** #EBEDF0 fill, #969FAF text, 16px/500, 4px radius, padding 0px 8px.
- **button-primary-hover:** background #FFFFFF, text #1C1E21 on hover.
- **input-field (“Language”):** #EFEFEF fill, #000000 text, 16px/400, padding 5.6px 10.4px, border 1px solid #767676.
- **card:** #FFFFFF0F fill, #FFD79A text, 16px/400, 6.4px radius, padding 16px, border 1px solid #A26B144D.
- **link:** transparent fill, #E2A843 text, padding 0px.

## Do's and Don'ts

- Do use #2E2A24 for the page.
- Do keep text in 2 levels: #FFFFFF, #999999.
- Do use #E2A843 as the brand accent: header, logo and key highlights.
- Do reuse the measured spacing steps (5.6px, 16px, 20px).
- Do use 6.4px corners on most elements; larger surfaces also use 4px.
- Don't add drop shadows for depth; use borders and contrast.
- Don't introduce new font families beyond system-ui.
- Don't use #E2A843 for large backgrounds or body text.
