Primary colours: are in the centre of the colour wheel: red, yellow and blue.
Secondary colours: are produced from the mixing of one primary colour with another. These colours are orange, green and violet.
Tertiary colours: are created whten mixing one secondary and one primary colour. i.e. blue + violet = blue-violet. The tertiary colours are: yellow-orange, red-orange, red-violet, blue-violet, blue-green and yellow-green.
Complementary colours: are opposite on the colour wheel. Red and green, yellow and violet, blue and orange, are the three simple pairs of complementary colours. These colours always go well with each other.
Warm colours: are colours we associate with the sun and fire. They are red, yellow and orange.
Cool colours: are colours we associate with the sea and cold, chilly weather. They are blue, green and some kinds of purple (blueish purple).
Adding white to a colour is known as a tint and adding black to a colour is referred to as a shade.
