How to Choose Composite Decking Colour

Introduction

In the world of landscaping and design, the importance of selecting the right colour doesn’t just come down to aesthetics.

In this article, we will discuss the different reasons why your choice of colour goes beyond looks, impacting everything from the deck’s visual appeal to the deck’s physical performance.

What are the crucial factors to take into consideration when shopping for composite decking online or in-store?

Colour Compatibility

Many homeowners start by considering the architectural style and colour palette of their property. We recommend choosing decking colours that align with existing features of your home, such as your window frames, bifold doors, exterior doors, or even your garden furniture.

Creating this alignment results in a cohesive, unified look for your outdoor living space. The best way to ensure a perfect match is to order free samples from your supplier. You can hold these samples against your home’s exterior to see exactly how the colours complement your property. Getting this match right doesn’t just look good—it boosts your home’s curb appeal and can even increase your property value.

Visual Example: Watch the video to see our Mixed Brown boards used in a natural cottage setting, compared to Anthracite Grey boards on a modern, upgraded Tudor-style home.

Sunlight Exposure

Before choosing a colour, consider the location of your new deck. Will the area be exposed to direct sunlight for long periods, or will it be shaded? Why is this important? Dark colours absorb significantly more heat from the sun—just like you feel hotter when wearing dark clothes on a sunny day.

Top Tip: For decking that sits in constant sunlight, it is better to choose light colours if you plan on walking barefoot. If your garden is shaded or heat isn’t a concern, you can safely choose any colour you like. Review our video below featuring light grey projects to help you decide.

Coordinate the colours with your indoor floor

Another design that many homeowners consider when purchasing composite decking is selecting a colour that matches the interior flooring of their home.

By selecting a colour that is the same or is very close, the transition from the interior of your home to the exterior of your home is seamless. This design is very impressive when the height of the decking is flush with your interior flooring.

Be familiar with undertones

Some composite decking boards feature complementing undertones within their surface design. These are typically found in high-quality woodgrain and embossed finishes.

While boards with multi-tonal designs often come at a premium price, they offer significantly more aesthetic value. The undertones add depth to the board, enhancing the overall colour to make it look more like natural timber.

Visual Example: A perfect example of a board with complementing undertones is the Ipe board. As you can see in the video, this product is a light brown colour, but it also features small pigments of redwood within the surface. These tones amplify the overall look, creating a rich, authentic finish.

Surrounding landscape

By taking your surrounding landscape into account, you can make a much smarter design choice. The existing trees, flowers, and natural elements in your garden play a huge role in how well your new decking blends with your property.

For example, gardens filled with flowers and natural beauty are often best suited to authentic, natural tones like Oak or Chocolate. These colours replicate real timber and sit harmoniously alongside green foliage.

Visual Example: Watch the video to see our real-life projects brought to life. Notice how the warm natural brown boards perfectly complement the surrounding colourful plants to create a vibrant, living landscape.

See the Colours for Yourself

Many online tools let you visualise different decking colours with various house designs. It can be helpful to play around with these tools and browse the different colours on offer before purchasing composite decking materials. If you have settled on a colour choice, you can order samples. Doing so helps you confirm the colours and make the necessary changes to your decisions.

This way, you can save the trouble of buying the wrong colour for your decking; after all, you will need to live with your colour choice of composite decking for many years and therefore want to get it right the first time. 

Conclusion

When selecting your composite decking colour, you must consider other factors besides which colour is your favourite. By taking into account the things we have discussed in this article, we hope that you can make a better decision when purchasing your new outdoor living area.
