Choose a harmony scheme or leave it on random, press Generate, and copy individual HEX codes or the whole palette in one click.

Analogous (neighbouring hues), complementary (opposite hues), triadic (three evenly spaced hues), monochrome (one hue at different lightness) and a random scheme that picks one for you.
Yes. Each swatch has its own copy button for the HEX code, and Copy all puts every code on your clipboard as a single comma-separated line, ready for CSS variables.
