Analogous colours sit next to each other on the colour wheel. They usually work in harmony and create harmonious designs. Select a primary color to dominate, and the other two as support and/or accent colours
Complementary colours sit opposite each other on the color wheel (e.g. red and green). When used together, they create strikingly vibrant palletes. Use sparingly with enough balance of white space
Rectangle or tetradic colour scheme uses four colors arranged into two complementary pairs allowing plenty of possibilities for pallette variations. Allow one colour to be dominant, and then pay attention to the balance between the warm and cool.
Split-complementary colours is a variation of the complementary color scheme which creates a strong vibrant pallette, but has less tension. This is a good choice for beginners, because it is easier to apply than complementary colours.
Square color scheme is close to the rectangle, but with all colors spaced evenly around the colour wheel. Allow one colour to be dominant, and then pay attention to the balance between the warm and cool.
Triadic colours are evenly spaced around the color wheel in the shape of a triangle, and in general, tend to create vibrant pallettes. Select a primary color to dominate, and the other two as support and/or accent colours
