split-complementary: one key color and two colors adjacent to that key color’s complement
triadic: colors evenly spaced on the color wheel
tetradic: key color and three more colors, all equidistant from the key color on the color wheel (double-complementary color scheme)
square: four colors spaced evenly around the color wheel
monochromatic: use a single base hue and extend the color scheme by using different shades, tones, and tints of that color family
