A colour wheel is a circular diagram divided into segments, featuring primary colours, and used to visualize the result of colour mixing.
Colour wheels can enhance understanding of colour relationships and assist with the accurate selection and reproduction of colours.
A colour wheel starts with segments representing primary colours. Additional segments are added between them to explore the outcome of mixing adjacent primary colours.
By adding more segments between existing ones, further mixing of adjacent colours can be explored.
A colour wheel exploring the additive RGB colour model starts with red, green, and blue primary colours.
A colour wheel exploring the subtractive CMY colour model starts with cyan, magenta, and yellow primary colours.
