# Site Palette — Full Reference

> Site Palette is a free browser extension (Chrome and Firefox) that extracts comprehensive color palettes from any website. Designers and frontend developers use it to capture accurate color schemes from live pages and export them to popular design tools.

This document is the extended machine-readable reference for AI agents and language models. The shorter [overview](https://palette.site/llms.txt) is recommended for quick context.

## What it does

Site Palette analyzes the rendered pixels of any web page and produces a color palette using one of three extraction algorithms:

- **Color Cube** — quantizes the color space into a cube and selects representative colors from densely-populated cells. Best for screenshots with many distinct hues.
- **Material Design** — extracts a palette aligned with Google's Material Design color system. Best for app and product UI work.
- **Median Cut** — recursive partitioning of the color space along the channel with the highest variance. Best for photography-derived palettes.

Once a palette is extracted, the user can:
- Copy any swatch as HEX, RGB, or HSL with a single click
- Download the palette as SVG, Sketch Template, Adobe Swatch (`.ase`), or a PNG sheet
- Send the palette directly to Google Palette or Coolors for further editing
- Save the palette to a personal profile and share it via a public link

## Who it's for

- **Frontend developers** capturing brand colors from competitor or reference sites
- **UI/UX designers** building mood boards and reverse-engineering visual systems
- **Brand consultants** auditing color usage across a portfolio of sites
- **Educators** demonstrating color theory with real-world examples

## Install

## Comparison with alternatives

Site Palette is most often compared against these browser extensions:

- **Color Palette** — simpler, free, copy-only. Lacks export formats, profile sync, integrations. See https://palette.site/vs-color.
- **Extract Colors DevTool** — has a built-in ruler and screenshot capture but no Sketch/Adobe/SVG exports, no Google Palette/Coolors integration, no profile. See https://palette.site/vs-extract.
- **Website Color Palette** — minimal extension supporting only HEX/HSL/RGB copy. No saving, no downloads, no integrations. See https://palette.site/vs-website.
- **Other browser extensions** — overview at https://palette.site/comparison.
