Colour Psychology: How Paint Colours Affect Mood

Have you ever walked into a room and immediately felt calm, energised, or even a little anxious without knowing why? The colours that surround us influence our emotions more than we realise. From the walls of your bedroom to the accents in your kitchen, colour plays a powerful role in setting the tone and atmosphere of your home.

In this guide, we’ll explore the fundamentals of colour psychology and how paint colours can affect your mood. Whether you're planning a home makeover or simply curious about the science of shades, this article will help you choose colours that create the emotional experience you want in every room.

What is Colour Psychology?

Colour psychology is the study of how colours influence human behaviour and emotions. Different hues can trigger emotional responses, change perceptions of space, and even impact physical wellbeing. This makes it a powerful tool in interior design, helping you create rooms that feel exactly how you want them to.

The Emotional Effects of Popular Paint Colours
