Frequently Asked Questions

How do I generate a color palette?
Pick or paste a base color, choose a harmony rule such as complementary or analogous, and the generator produces a matching set. You can lock favorites and regenerate the rest until the palette feels right.
What is a complementary color scheme?
A complementary scheme pairs colors from opposite sides of the color wheel, such as blue and orange. It creates high contrast and visual energy, making it good for calls-to-action and accents.
What color formats can I copy?
This tool outputs HEX (#3a4796), RGB (rgb(58,71,150)) and HSL (hsl(232,44%,41%)) so you can paste values straight into CSS, design tools, or brand guidelines.
How many colors should a palette have?
A practical palette has one dominant color, one or two supporting colors, and one accent — roughly three to five colors. Too many competing colors weaken visual hierarchy.
