Live color harmony tool. With JavaScript enabled you can pick a base color or type a hex code and instantly see five sets built from it: its analogous neighbours, its complementary opposite, its split complementary pair, its triadic trio and its tetradic quartet. It loads on a random color, so try your own next.
A scheme tells you which hues agree, not how much of each to use. That second part is where palettes are won or lost. A reliable starting point is to let one color cover most of the surface, a second carry the supporting areas, and a third appear only as the occasional accent. Pick the harmony for the relationship, then spend the colors unevenly. This is why the themes we build lean on one dominant background hue with a small, well chosen set of accents drawn from a single scheme. The harmony keeps the colors related; the proportions keep them calm.
If you want to keep exploring, our palette generator lets you build a palette by hand, pull one straight out of an image, or roll a random one, then check its harmony and copy the hex codes, so you can create your own color palette with harmony and turn any of these ideas into something you will actually ship.
