Color choices should feel easier.

ColorThemePicker is a free set of browser-based tools for exploring palettes, checking readability, and moving from color inspiration into an actual design.

What you can do here

Generate analogous, complementary, triadic, and monochromatic combinations. Browse curated themes, customize swatches, preview interface layouts, test text contrast against WCAG thresholds, extract prominent colors from an image, and export reusable code.

Made for practical design work

Our original six semantic themes were published on this site before the redesign; this edition also adds 24 five-color palettes and a browser-only Image-to-Theme workflow. Our focus is not on claiming that one color combination is objectively the best. Color decisions depend on content, context, usability, and audience. The tools help you explore quickly; a finished design still benefits from accessibility and real-device review.

How we explain our results

Our methods and limitations page explains the difference between deterministic contrast ratios and heuristic design audits. Our worked design exercises use transparent, fictional scenarios and reproducible HEX values, not invented client success stories.

What happens to your files?

Color extraction runs directly in your browser and does not upload your images to a ColorThemePicker backend. Favorites are stored on your device using browser storage. See our Privacy Policy for details.
