Image Color Palette Generator

Generate colors from an image in-browser, then evaluate accessibility and reuse the palette in design outputs.

Choose an imageColors are estimated from sampled pixels and grouped locally.

Dominant-color prevalence & developer export

Use the image already selected above, but treat palette extraction as a distribution problem rather than repeated eyedropping. Choose palette size and minimum color separation, rank representative colors by pixel prevalence, then export CSS custom properties or JSON with shares.

Dominant colors are estimated from a downsampled local image and quantized RGB buckets. Prevalence helps palette selection; it does not claim perceptual color-management accuracy or ICC-profile conversion.

Color and accessibility boundaries

HEX/RGB/HSL/HSV/OKLCH conversions are numerical color-model operations. CMYK output is an RGB-derived approximation rather than ICC-profiled print proofing. WCAG contrast ratios measure luminance contrast only and do not certify a full interface. Color-blindness previews are design simulations, not medical tests.
