Frequently asked questions

What is a complementary color scheme?+

Complementary colors sit opposite each other on the color wheel. Paired carefully they create high contrast and visual energy — great for calls to action.

How many colors should a brand palette have?+

A practical brand palette is usually three to five colors: one or two primaries plus supporting and neutral tones. This tool generates five to give you range.

Can I enter my own hex color?+

Yes. Type any hex value into the base color field, or use the color picker, and the palette updates instantly.

Is the color palette generator free?+

Yes. It's completely free, runs in your browser, and requires no sign-up.
