How to use a colour wheel
A colour wheel shows you how colours relate to each other and visually demonstrates the relationship between primary, secondary and tertiary colours. You can use the colour wheel to develop colour schemes with these several key approaches.
Monochromatic
This is a variation of a single colour. Monochromatic schemes are serene and relaxing. Light tones create a relaxed delicate feel, whereas dark tones can feel moody and dramatic. Mixing light and dark tones adds interest and a touch of energy.
Complementary
These colours can be found on the opposite sides of the colour wheel, such as blue and orange, red and green or purple and yellow. Used together, the colours appear brighter
Split Complementary
The split complementary colour scheme is a variation of the complementary colour scheme. In addition to the base colour, it uses two colours adjacent to its complement. This colour scheme features less contrast, making it for the less confident.
Contrasting
Colours that are not in the same colour “family” or that aren’t exactly harmonious can work very well together. By using a bold or deep colour from one area of the colour spectrum and using a lighter colour from a different family, the overall impact can be quite striking.
Triadic
This approach uses three different colours on the colour wheel. They can be monochromatic, complimentary or contrasting. The results are harmonious but are a little more vibrant.
Keep undertones the same. Varying undertones can sometimes be more visible in certain environments, so don't use too many undertones if you're not confident with colour.
