Which color harmonies are supported?

Random, complementary (2), analogous (3-8), triadic (3), tetradic (4), split-complementary (3), and monochromatic (3-8). Fixed harmonies return their natural swatch count even if you set a higher target.

What formats can I copy?

Each swatch shows HEX, RGB, and HSL. Use Copy HEX list (one per line), Copy HEX row (comma-separated), or Copy CSS for a :root block with --color-1 style variables.

Can I start from my brand color?

Yes. Paste a HEX value like #3b82f6 or use the color picker. Shuffle picks a fresh random base while keeping the selected harmony.

Does this check WCAG contrast?

No. This tool focuses on harmony palettes and export formats. Pair swatches with a contrast checker when you need AA/AAA text verification.

Does my palette leave the device?

No. The Color Palette Generator runs entirely in your browser. Colors are not uploaded or stored on a server.
