Build a palette from any base color using six harmony rules: complementary, analogous, triadic, tetradic, split-complementary and monochromatic. Copy as CSS, Tailwind or JSON.
Complementary colors sit opposite each other on the color wheel (180 degrees apart) and create high visual contrast when paired.
Analogous color schemes use 3 colors adjacent on the color wheel (within 30 degrees) and appear naturally harmonious.
