Colour schemes/ Colour Palettes/ Colour Harmonies
Monochromatic harmony uses various values (tints, tones, and shades) of the same colour.
Analogous harmony employs colours that are next to each other on the color wheel. These colours match well and create serene and comfortable designs.
Complementary colours are colours that appear opposite of each other on the colour wheel. The high contrast of complementary colors creates a vibrant look especially when used at full saturation.
Triad colours are three colors equally spaced from one another, creating an equilateral triangle on the color wheel. Primary and secondary colours are examples of triad colours.
Tetrad harmony consist of 2 sets of complementary colours with equal distance from each other.
