Build polished color systems without guesswork

This online color palette generator creates coordinated color combinations for websites, applications, branding, presentations, illustrations, social content, and other creative projects.

Start from a seed color or generate a completely fresh combination. Harmony modes apply practical color theory relationships while controlled variation prevents every palette from looking mechanical or repetitive.

Each swatch includes editable color values and automatic black-versus-white contrast guidance. You can lock the strongest colors, generate alternatives around them, and export the finished palette in a format that fits your workflow.

The built-in image palette extractor samples an image and groups similar pixels into representative colors. This is useful for building a visual identity from product photography, artwork, interiors, landscapes, or existing brand material.
