What the Dominant Colour Palette Extractor does

Sample every pixel of an uploaded image, bucket similar colours together and return the five most dominant hex codes with a visual swatch preview. Ideal for building a palette that matches a photo or logo. The Dominant Colour Palette Extractor keeps every equivalent representation of a color in sync — HEX, RGB, HSL and named CSS values — so you can copy whichever format your target file expects.

The math is done with the standard sRGB gamma curve so the numbers match what design tools such as Figma, Sketch and Photoshop produce for the same swatch.

Why the Dominant Colour Palette Extractor is useful

Everything runs locally, so brand palettes, unreleased product colors and client work stay on your device. There is no upload and no logging.

Pair the Dominant Colour Palette Extractor with the HEX to RGB and RGB to HEX tools to move quickly between design and code, or with the CSS Beautifier to drop the finished values into a stylesheet.

Also known as: color palette from image, dominant color extractor, image color picker, free dominant colour palette extractor, online dominant colour palette extractor, dominant colour palette extractor online free, dominant colour palette extractor tool.

Real-life use cases

Design-to-code handoff

Designers work in HEX, stylesheets often want HSL or rgb(). Converting keeps the palette identical across both.

Building a consistent theme

Nudging lightness and saturation values gives you tints and shades that belong to the same family.

Accessibility work

Precise numeric values are the starting point for checking contrast and adjusting a palette until it passes.

Tips for the best results

  • Keep hue steady and vary lightness to build tints and shades that match.
  • Store colors as CSS variables so a theme change is a one-line edit.
  • Always verify contrast for text colors before shipping them.
