Colour Psychology in Design: Transforming Spaces With Hue and Tone

Colour psychology in design is a fascinating and complex subject that helps explain how colours influence our emotions, perceptions, and overall experience of a space.

Understanding the psychological effects of different colours can help you create interiors that evoke specific moods and atmospheres, making your home aesthetically pleasing and emotionally nurturing.

The basics of colour psychology

Colour psychology is the study of how colours affect human behaviour and mood. Colours can evoke a wide range of emotions and reactions, from calm and relaxed to excitement and energy. In interior design, the strategic use of colour can transform a space, making it feel larger, cosier, more vibrant, or more serene.

Colours and their psychological effects


Red is a powerful colour that can evoke strong emotions such as passion, excitement, and even anger. It is often used to create a focal point or add warmth to a space. However, too much red can be overwhelming, so it’s best used as an accent.


Blue is known for its calming and soothing effects. It can create a sense of tranquillity and relaxation, making it an excellent choice for bedrooms and bathrooms. Light blues can make a space feel larger and more open, while darker blues add a sense of sophistication and depth.


Yellow is associated with happiness, optimism, and energy. It can brighten up a space and make it feel more welcoming. However, too much yellow can be overstimulating, so it’s best used in moderation.


Green represents nature and tranquillity. It has a calming effect and can help reduce stress. Green is versatile and works well in almost any room, promoting a sense of balance and harmony.


Orange combines the energy of red and the cheerfulness of yellow. It’s an energetic and enthusiastic colour that can create a lively atmosphere. It’s great for social spaces like living rooms and kitchens but should be balanced with neutral tones to avoid overstimulation.


Purple is associated with luxury, creativity, and calmness. Lighter shades like lavender can create a peaceful environment, while darker shades like royal purple add a sense of elegance and sophistication.

Practical applications of colour psychology in interior design

By strategically using colours, you can transform your living space to reflect your desired atmosphere, functionality, and aesthetic, ensuring each room feels both harmonious and distinct.

  • Creating a mood

The mood you want to create in a room should guide your colour choices. For instance, if you want a space to feel calming and restful use cool colours like blue and green. For a more energetic and stimulating environment, choose warm colours like red, orange, and yellow.

  • Defining spaces

Colour can be used to define different areas within an open-plan space. For example, a dining area can be painted a different colour from the living area to create visual separation. This is especially useful in modern homes with open layouts.

  • Enhancing the perception of space

Colours can influence how we perceive the size and shape of a room. Light colours can make a small room feel larger and more open, while dark colours can make a large room feel cosier. For instance, using light blue on the walls can give the illusion of more space and airiness.

  • Balancing colour schemes and materials

A well-balanced colour scheme typically includes a mix of primary, secondary, and neutral colours. Neutrals like white, grey, and beige can provide a backdrop that allows bolder colours to stand out without overwhelming the space. For example, in a room with neutral walls and furniture, a timber dining table with a natural wood finish can add warmth and interest without clashing with other colours.

  • Highlighting architectural features

Use colour to draw attention to architectural features such as mouldings, fireplaces, or built-in shelves. Painting these elements in a contrasting colour can make them stand out and add character to the space.

  • Coordinating with furniture and decor

When selecting colours, consider how they will interact with your existing furniture and decor. For instance, if you have a striking piece like a TV unit from Melbourne in your living room, choose a wall colour that complements rather than competes with it. You can find unique pieces in a furniture sale in Melbourne to match your colour scheme while on a budget.

The impact of colour combinations

Monochromatic schemes

Monochromatic colour schemes use variations of a single colour to create a cohesive and elegant look. This approach can make a room feel harmonious and visually appealing. For instance, different shades of blue can create a calming and sophisticated atmosphere in a bedroom or living room.

Analogous schemes

Analogous colour schemes use colours that are next to each other on the colour wheel, such as blue and green or red and orange. These combinations are naturally harmonious and pleasing to the eye, making them ideal for creating a cohesive look in any room.

Complementary schemes

Complementary colour schemes use colours that are opposite each other on the colour wheel, such as blue and orange or red and green. These combinations create a vibrant look that can add energy to a space. Use complementary colours sparingly to avoid overwhelming the room.

Triadic schemes

Triadic colour schemes use three colours that are evenly spaced around the colour wheel, such as red, yellow, and blue. This approach offers a balanced and lively colour palette that can create a dynamic and engaging environment.

Colour psychology enables you to create spaces that look beautiful and support or enhance your emotional and psychological state. By understanding how different colours influence mood and perception, you can make informed choices that enhance the functionality and aesthetic appeal of your home.

Whether you’re choosing colours for a new home or updating an existing space, consider how each hue will affect the atmosphere and use of the room. From calming blues to energising yellows, the right colours can transform your home into a sanctuary that reflects your style and meets your needs.
