Colour is named by three major elements;
- Primary: Red, Blue and Yellow (these are pure hues and cannot be derived from any other colours)
- Secondary: Green, Purple (Violet), and Orange (created by mixing primary colours)
- Tertiary: these are created by mixing uneven quantities of primary and secondary colours
The use of a colour wheel helps the user identify the above elements and also assists in identifying warm (aggressive) or cool (receding) colour palettes.
It also assists in creating a colour scheme by identifying colour relationships such as; monochromatic,complementary, split-complementary,triad, tetrad and analogous.
