ColorHub is a free web app for finding pre-made six-color palettes, with sorting by popularity, favoriting, a hex color picker, and a built-in contrast checker.
The six-color format gives more range than the four- or five-color palettes most generators default to, which matters for a project that needs a fuller system (primary, secondary, accent, and neutrals) rather than just a hero color pair.
Designers who need a fuller, six-color starting palette rather than the shorter sets most palette generators produce by default.
Use the built-in contrast checker on a shortlisted palette before committing. It saves a trip to a separate accessibility tool once you've narrowed down the options.
