Colour Theory!

    The colour wheel is divided into three different categories: primary, secondary, and tertiary.

Primary: three primary colours are: red, yellow and blue. These colours are considered to be foundation colours because they are used to create all other colours.

Secondary: combining two of the primary colours, three secondary colours are formed. 

Tertiary: the six tertiary colours are made by combining a primary and an adjacent secondary colour. These are: yellow-orange, orange-red, red-violet, violet-blue, blue-green, and green-yellow.

 Warm colours: bright, passionate and tends to be eye catching colours. Warm colours include red, orange and yellow and also variations of those three colours.

In the make-up artistry, reds can be both cool and warm. If the red is blue based it is cool, but if the red is orange based it's warm.

Cool colours: normally seen as calm, soothing colours. Cool colours include violet, blue and green.

In make-up the same theory applies with the colour green. If the green has more gold/yellow undertone then it is warm. However if the green contains more blue undertone then it is cool.

Analogous: looks created by using three or more colours that are next to each other on the colour wheel.

Complementary: created by combining colours from opposite sides of the colour wheel.
