The Three-Colour Rule in Interior Design

The three-colour rule is a fundamental concept in interior design that helps create a

harmonious and visually appealing space. This guideline simplifies the process of selecting

colours and ensures a balanced and cohesive look in any room.

Understanding the Three-Colour Rule

The three-colour rule involves using three main colours in a room's colour palette. These

colours are typically divided into three categories:

Dominant Colour: This is the primary colour of the room and should make up about 60%

of the space. It sets the overall tone and mood, forming the foundation of the room's

design. Typically, this colour is applied to the walls, large furniture pieces, and flooring.

Secondary Colour: Making up about 30% of the room, the secondary colour is used to

add depth and interest. It complements the dominant colour and is often found in

upholstery, window treatments, and smaller furnishings. This colour should support and

enhance the dominant colour without overpowering it.

Accent Colour: The accent colour accounts for the remaining 10% of the space. It is used

in smaller doses to add pops of interest and excitement. This can include decorative

items such as throw pillows, artwork, vases, or lamps. The accent colour is typically

bolder or more vibrant, drawing attention and adding character to the space.

Benefits of the Three-Colour Rule

Simplicity: By limiting the colour palette to three main colours, the process of selecting

and coordinating colours becomes more straightforward, reducing the likelihood of

clashing hues.

Cohesion: Using a defined set of colours helps create a unified look, making the room feel

more put-together and intentional.

Flexibility: The rule allows for flexibility and creativity within a structured framework.

Designers can play with dierent shades, tones, and textures of the chosen colours to add variety and interest.

Tips for Implementing the Three-Colour Rule

Choose a Neutral Base: Start with a neutral colour as your dominant colour to provide a

versatile backdrop. This makes it easier to incorporate other colours and adapt the space

over time.

Consider the Mood: Think about the mood you want to create in the space. Cool colours

like blues and greens can evoke calmness, while warm colours like reds and oranges can

add energy and warmth.

Balance is Key: Ensure that the colours you choose are balanced throughout the room.

Avoid concentrating too much of one colour in a single area.

Experiment with Textures: Incorporate different textures and finishes to add depth and

interest without deviating from the colour scheme.

By following the three-colour rule, you can create a well-balanced and aesthetically pleasing interior that reflects your personal style while maintaining a sense of harmony.
