About the Color Palette Extractor

Extracting a color palette from an image is a common task in design systems work — matching a brand's photography, building a theme from a logo, or generating a cohesive color scheme from a reference image. This tool extracts the dominant colors from any image using pixel quantization, and exports the palette in CSS, Tailwind, and JSON formats ready for your design system.

What this tool does

Color Extraction

Extracts 4–16 dominant colors from any image using pixel quantization. Configurable color count and sampling strategy.

Multiple Export Formats

Export as CSS custom properties, Tailwind color config, JSON array, or plain hex list — ready for your design system or codebase.

Contrast Checking

WCAG contrast ratio for each extracted color against white and black backgrounds — identify which colors are accessible for text use.

100% Client-Side

All processing uses the browser's Canvas API. Your images are never uploaded or transmitted anywhere.

Pipeline

  • Color Converter — convert extracted hex values to HSL, RGB, OKLCH, or CMYK.
  • SVG Optimizer — optimize SVG icons before applying your extracted palette.

Frequently asked

Is my image sent to a server?
No. All color extraction runs 100% in your browser using the Canvas API. Your images never leave your device.
How does color palette extraction work?
The tool samples pixels from your image and clusters similar colors together using a quantization algorithm (median cut or k-means). The most representative colors from each cluster become the palette. The number of colors is configurable.
What image formats are supported?
JPEG, PNG, WebP, GIF, and SVG. The image is rendered to a canvas element and pixel data is read via the Canvas API.
What is the difference between dominant colors and a balanced palette?
Dominant colors are the most frequently occurring colors in the image — often backgrounds and large areas. A balanced palette samples from across the color spectrum of the image, including accent colors that appear less frequently but are visually important.
Can I export the palette as CSS variables or Tailwind config?
Yes. The tool exports palettes as CSS custom properties (--color-1: #hex), Tailwind color config, JSON, and plain hex lists — ready to paste into your design system.
