Colour Theory

Colour theory can be overwhelming to understand and teach. 

AccessArt would encourage an intuitive approach to teaching colour through resources such as Expressive Painting and Colour Mixing, however the information below will help you understand some of the terminology used in colour theory.

Primary Colours

Primary colours are any of a group of colours from which all other colours can be achieved by mixing. Red, yellow and blue can’t be recreated through colour mixing and act as the building blocks for all other colours.

Tertiary Colours

Tertiary colours can be achieved by mixing primary and secondary colours. Blue-green, blue-violet, red-orange, red-violet, yellow-orange and yellow-green are colour combinations you can make from colour mixing. On a colour wheel, tertiary colours are between primary and secondary colours. – Adobe
