Colour Psychology: How a Room’s Colour Affects Mood

Home decor is seen by many as just a simple matter of aesthetics; you decorate according to your individual tastes and preferences, tailoring it to match the space. While most of us think very little about room colour, some are of the opinion that it affects us more than we realise. Proponents of colour psychology believe that room colour can influence your mood and thoughts, having a profound effect on the emotional well-being of you and your family.

Red is an intense colour, and is believed to raise blood pressure, speed respiration, and heart rate. It’s a good choice when you want to stir up excitement and stimulate conversation.

Yellow is energising and uplifting, communicating joy and happiness. However, while it is a cheery colour, yellow in large amounts can create feelings of frustration, anger, and even depression. It’s best used in moderation in a colour scheme.

Blue is considered calming. It’s said to be able to bring down blood pressure and slow the heart rate. Softer shades of the colour are relaxing, while dark blues can evoke feelings of sadness. Be careful, though; a pastel blue can come across as unpleasantly chilly, especially in a room that receives little natural light.

Green is thought to be the most restful colour for the eye. It has a calming effect when used as the dominant colour in decorating and is believed to relieve stress by helping you relax. Green tones have all the cooling hues of blue but with enough warmth to promote comfort and togetherness.

Purple is rich, dramatic, and sophisticated. It’s associated with luxury and creativity, and when used as an accent colour, it gives a room unparalleled depth. Lighter shades of purple have the same restful qualities as blue but without the risk of feeling chilly.


Orange interior

Orange evokes excitement, enthusiasm, and energy, so it’s best avoided in rooms where you want to relax. It’s also a happy colour and the perfect choice if you’re looking to invigorate an otherwise sedate space.

Neutrals – Black, Grey, White, and Brown

These are the basic tools in any interior designer’s kit. Neutral colour schemes fall in and out of fashion, but they add flexibility to a space – they can be used to liven things up, or to calm things down.


Living Room, Entrance Hall, and Foyer

Warm tones such as reds, yellows, and oranges often work well in these spaces as they supposedly encourage people to sit around and talk, replicating the warmth of the colour in their perceptions and reactions to you and your family.


Many people opt for neutral shades in the kitchen, which is fine, but reds and yellows are particularly effective colours to use in this space. Be careful with red, though – it’s believed it can prompt you to eat more, so you might want to keep it away from the fridge.

Dining Room

Red is perfect for this room – it encourages conversation, keeps the room warm and cosy, and promotes a healthy appetite.


The bedroom is where you go to relax, unwind, and sleep. Cool colours – blues, greens, and lavenders – can be used to great effect here as they are thought to have soothing properties.


White has always been a popular choice in bathrooms, in large part because it signifies cleanliness and purity. But for some, the bathroom is a private retreat for relaxation and rejuvenation, which is why blues, greens, and turquoises make such good colour choices.

Pale blues are the perfect choice for bathrooms.

Exercise Room

Reds and oranges can help you move, but they also have a tendency to make you feel overheated. For this reason, cooler yellow-greens and blue-greens are the best option, and they make you feel happier too.

Home Office

Being as productive as possible means you’ll complete your work faster and have more time to spend with family and friends. Green is the best choice for the home office, because it aids and improves concentration.
