If you have ever walked into a room and felt that something was off, but could not say why, colour balance is often the culprit. The 60 30 10 rule is a simple guideline that helps you spread colour across a space so it feels settled and intentional. It has been used in decorating for many years, and it remains one of the most practical tools for anyone planning a renovation, styling a new rental or simply refreshing a single room.

What Is the Rule, Exactly?

The idea is to divide the colours in a room into three groups by proportion. Sixty per cent of the space is taken up by a dominant colour, thirty per cent by a secondary colour, and the remaining ten per cent by an accent. The numbers are not meant to be measured with a ruler. They are a way of thinking about how much visual weight each colour carries, so that no single shade competes for attention.

The dominant colour usually covers the largest surfaces, such as walls, large rugs and sometimes a big sofa. The secondary colour supports it and adds interest through items like armchairs, curtains, bedding or cabinetry. The accent is the small pop of contrast, found in cushions, artwork, vases, lamps or a single statement chair.

Why the 60 30 10 Rule Still Works Today

Design trends shift quickly, but the logic behind the 60 30 10 rule does not rely on any particular style. Whether your home leans towards warm neutrals, earthy greens, coastal tones or deeper, moodier shades, the proportions help the palette hold together. That flexibility is a big reason the rule continues to appear in design advice year after year.

It also suits the way many Australians live now. 

Open-plan layouts are common, which means one colour scheme often needs to flow across the kitchen, dining and living areas. Using the same three-part structure throughout keeps these zones connected without making them look identical. For renters, it is equally useful, because the 30 and 10 portions can be changed through soft furnishings and decor without touching the walls.

Another benefit is that the rule makes decisions easier. Rather than choosing from hundreds of paint swatches and homewares with no framework, you start with a clear structure and fill it in one step at a time.

How to Choose Your Three Colours

Start with the dominant colour, since it sets the tone for the whole room. Many people choose a soft neutral such as warm white, greige or pale sand, because these colours work well with natural light and are easy to build on. If you prefer something bolder, a muted sage or a deep navy can work just as well, provided the room receives enough daylight.

Next, pick the secondary colour. It should complement the dominant shade without matching it exactly. If your walls are a light neutral, a mid-tone such as terracotta, olive or dusty blue can add depth. Timber floors and furniture also count as part of your palette, so take them into account before buying anything new.

Finally, choose the accent. This is where you can be a little more adventurous, because it only makes up a small part of the room. A rust orange against green, or mustard against navy, can lift the whole space. If you are unsure, hold fabric samples or paint swatches together in the room at different times of day, since lighting can change how colours appear.

Applying the Rule Room by Room

In a living room, you might paint the walls a warm neutral, choose a sofa and curtains in a muted green, and add accents through cushions, a ceramic lamp base and a piece of art. In a bedroom, the bedding and a feature chair often serve as the secondary colour, while a throw or bedside lamp provides the accent.

Kitchens and bathrooms follow the same logic, though fixed elements play a larger role. Tiles, benchtops and cabinetry often form the dominant and secondary colours, so the accent can come from towels, stools, tapware or plants. Working with these fixed features first prevents costly mistakes later.

When to Bend the Rule

The 60 30 10 rule is a starting point rather than a strict requirement. Textures and patterns can complicate the balance, since a heavily patterned rug may count as both the secondary colour and the accent. Some rooms also work better with a more minimal approach, such as a single neutral base with one accent colour. An interior designer will often adjust the proportions slightly depending on the size of the room, the amount of natural light and the mood the homeowner wants to create.

It also helps to repeat each colour in at least two places. This creates rhythm and stops an accent from looking like an afterthought. A cushion in the same tone as a piece of artwork, for example, ties the room together quietly.

A Reliable Framework for Any Home

The strength of this approach is its simplicity. It gives you a clear structure without dictating which colours you must like or which style you must follow. Whether you are working with a professional interior designer or making choices on your own, the proportions offer a dependable way to check that a room feels balanced. In 2027 and beyond, that kind of practical guidance is likely to stay useful, no matter which colours come in and out of fashion.
