Mixing | Single Pigment Colours

Technically, you only need the 3 primary colours (red, blue and yellow) to create any other colour for your palette but, by using both cool and warm single pigment colours, you can create clean secondary colours with a cool or warm bias. For example, by including a single pigment warm red and a cool red, as well as a warm and cool yellow, you can mix warm and cool oranges. Consider organizing a palette of 6 primaries, with two of each primary colour so that you have a cool and warm bias for each primary and will then be able to mix clean secondary colours with a bias of your choice. This will expand the range of colour options in your palette.
