Color Palette from Image Extract a harmonious color palette from any image using K-means clustering.

What Is Color Palette from Image?

A color palette extractor that uses K-means clustering to identify the most representative colors in an image. Unlike simple dominant color detection, K-means groups similar pixels into clusters and finds the centroid of each cluster, producing a harmonious and representative palette. Extract 3 to 12 colors with percentage distribution. Each color shows hex code and RGB values. Great for design inspiration and brand color extraction.

Why Use Color Palette from Image?

• K-means clustering for accurate color grouping
• Adjustable palette size from 3 to 12 colors
• Shows percentage distribution of each color
• One-click copy for hex and RGB values

Common Use Cases

Design Inspiration

Extract palettes from photos for design projects.

Brand Colors

Identify key colors from brand imagery or logos.

Color Theory

Analyze color distribution and relationships in artwork.

Web Design

Generate color schemes from hero images for consistent design.

Technical Guide

Image is downsampled to 200px max dimension for performance. Pixels are collected as RGB triples (skipping transparent). K-means clustering initializes centroids evenly spaced through the pixel array, then iterates 20 times: assign each pixel to nearest centroid, recalculate centroids as cluster means. Final colors are sorted by cluster size (percentage). The palette bar renders colors proportionally by their prevalence.

Tips & Best Practices

• 1
  6-8 colors gives the best balance of detail and usability
• 2
  Larger palette sizes capture subtle accent colors
• 3
  Photos with distinct subjects produce the clearest palettes
• 4
  Use the visual palette bar to see color proportions

Frequently Asked Questions

Q How does this differ from a simple color extractor?

This uses K-means clustering for more accurate grouping.

Q How accurate is it?

K-means produces representative centroids, not exact pixel colors.

Q Does it work with transparent images?

Transparent pixels are skipped in the analysis.

Q What copy formats are supported?

Click individual colors for hex, or Copy All for the full palette.

Q Are results reproducible?

Results may vary slightly due to K-means initialization.
