2023 Colour Trends and How They Benefit Your Project


Colorbond®, the iconic Australian steel manufacturer, continues to invigorate home-owners and builders alike with their recently released colour range, adding to their already extensive options.

These four new colours are highly versatile and each would make a huge impact on the look and feel of your client’s home or business.

In addition to being stylish and manufactured to the highest standards, each of the new colours are in-line with the government’s Climate Change Adaptation Strategy and includes four roofing colours with low and medium solar absorptance:

Dover White Endlessly compatible, this bright white unifies a tonal scheme or brings fresh contrast to darker colours where needed. 0.28
A cool grey with pale tones, it provides abundant possibilities to enhance concrete and pale timbers, or contrast against rich-coloured brick. 0.40
This relaxed and calming grey is reminiscent of mountain gums and coordinates easily with dark timbers and naturally honed stone finishes. 0.57
A sophisticated and tranquil blue-grey with a matt finish, which lends an added intensity to its confident blue tone. 0.59

Solar absorptance

Solar Absorptance is the proportion of the total incident solar radiation that is absorbed by the roof material with the remainder being reflected.

A roof with a lower solar absorptance will absorb less heat and will assist in cooling the roof space and the rest of the building.

Improve passive cooling and heating with lighter roof colours

Lighter roof colours reflect more light and absorb less heat, helping with passive temperature control and BASIX certification.

Australia’s average temperature increased by around 1.4 °C between 1910 and 2020, and the number of “extreme heat days” (over 35 °C) has risen 500% in only the last 30 years.

Most homes do not adequately heat or cool, which leads to homeowners using alternative heating and cooling solutions. This puts a strain on Australia’s resources and on our bank balances.

With the effects of climate change being felt around the world, it is becoming increasingly important to incorporate passive heating and cooling measures in building projects.

Appropriate ridge ventilation, window-shading and insulation, combined with lighter coloured roofs absorb less heat from the sun.

Additionally, lighter colours also help to reflect sunlight during winter months when heating is more important, improving passive heating efficiency without increasing glare.

This makes them an ideal choice in hot climates where passive cooling is key. Projects specifying lighter roof colours can enjoy cooler interiors during summer months, reducing their reliance on air conditioning and saving energy costs.

Blending into the surrounding environment or making a statement with colour

Blending into the surrounding environment

When choosing a roof colour it may be a consideration as to how it will fit in with the surrounding environment.

Reference the existing colour palette of the neighbourhood when selecting a roof colour in order to create an aesthetically pleasing roof profile.

Some projects may be designed to make a statement with colour.

A lighter coloured roof can stand out from its surroundings and elevate the look of a home, particularly for a modern mono-chromatic look or when appropriate contrast is applied.

BASIX Certification

The new colours will assist with BASIX compliance, ensuring there won’t be any delays or issues when applying for approval from local councils.

Benefits of designing projects with lighter colour roofs

The benefits of designing projects with lighter colour roofs include improved energy efficiency, a reduction in energy costs, better blending into surrounding environments and making a statement with colour.

When used in combination with other strategies such as ventilation, shading and insulation, light coloured roofs mitigate the effects of Australia’s extreme weather and also improve the air temperature inside the home.

Overall, lighter coloured roofs provide an effective way of adapting our homes for climate change without sacrificing style or comfort.
