A colour wheel is a tool used in drawing, painting, and other artistic disciplines. Beginning with basic colours, artists can create a wide range of colours by combining primary, secondary, and tertiary colours. Colours such as fuchsia can be made by knowing where they fall on the colour wheel so that you know which colours to combine. Once you've made fuchsia you can adjust how light or dark it is by adding white or black to the colour in small increments to create a full range of fuchsia gradients.
Place red, yellow and blue paint on your palette. These are the primary colours of the colour wheel, and all other colours can be made by combining these three colours in different ways.
Combine equal amounts of red and blue paint from your palette, mixing it thoroughly until the colour changes to a solid shade of purple with no streaks or variances. Purple is a secondary colour on the colour wheel, since it is created from two primary colours.
Combine equal amounts of the purple paint you created and your original red paint. As before, mix the paint thoroughly until the colour becomes solid. The colour you've created is fuchsia, a tertiary colour on the colour wheel created by combining a primary colour and a secondary colour.
Illustrate the colour wheel if it helps you to learn the positions of the colours. Paint red, blue and yellow in a triangular arrangement, then place purple between the red and blue. Your fuchsia should be between the purple and red, linking them and showing their connection. Additional secondary and tertiary colours can be mixed to fill in the spaces between purple and blue and also to show the secondary and tertiary colours between red and yellow as well as yellow and blue.
Other art materials such as clay, chalk, pastels and other colour items can be used to combine colours in the same way. The colour wheel shows the relationship of the colours and is not restricted to a single medium.
