Quick summary

To use colour theory effectively in home decorating, focus on creating harmony with schemes like complementary, monochromatic, analogous, triadic, or tetradic, based on your desired boldness or subtlety. Choose colours that sit opposite or next to each other on the wheel, balancing warm and cool tones to suit each room’s mood. Remember, less is often more—avoid overcrowding with too many colours, especially in tetradic schemes.

If you’re looking to give your home a makeover or you want to do your new extension justice, it’s time we let you in on a little industry secret: colour theory!

What is colour theory?

Okay, we said this was a secret but in fact, a lot of different industries know and use colour theory day to day, from artists to fashion designers. Why? It’s because colour theory is the science of combining colours.

In order to understand and use colour theory, you’ll need to grab yourself a colour wheel. You may remember seeing these back in school.

colour wheel - sized.

By using this colour wheel, you’ll be able to understand the relationship between various colours and which ones look good together. When two (or three) colours match up well together, it’s known as ‘a colour harmony’.

The purpose of colour theory is to provide practical ways of finding these colour harmonies through the use of the wheel.
