We reveal our favourite radiator & wall colour combinations

Colour wheels aren’t just for school art classes – they’re also a useful tool for interior design projects, especially if fabulous colour combinations are a priority. We’ve explained more, and shared some of our favourite radiator and wall colour pairings to help inspire your next renovation.

The colour wheel

Primary colours are red, blue and yellow. These are pure colours, which means you can’t create them from mixing others, and all other shades and colours are derived from them.

Secondary colours are orange, green and purple. These hues sit between the primaries on the colour wheel, and are formed when equal parts of two primary colours are mixed.

Tertiary colours are created by mixing a primary colour with the secondary colour next to it on the wheel. With each blending, the hues become less vivid, creating an entire spectrum of shades.

What are complementary and contrasting colours?

Complementary and contrasting colours are essentially the same thing. While “complementary” might suggest they sit side by side on the wheel, they actually sit opposite one another. With matching intensity, undertones and hues, neither colour dominates the other and instead they balance one another with perfect synchronicity.

Caroline, Managing Director at TRC, explains:
“A radiator can blend with the walls or be part of the contrasting colour to balance a scheme. A pop of a complementary colour in a radiator design that’s a little more quirky can turn a colour balancer into a statement at the same time.”

Capture interest with analogous colour schemes

Analogous schemes use three colours next to each other on the wheel:

a dominant primary or secondary colour
a supporting secondary or tertiary colour
and a third colour that’s either a mix of the two or a contrasting accent

Caroline explains:
“You can create a completely different look and feel just by moving one segment around the colour wheel. You can shift from decadent jewel tones to restful blues and greens. The most familiar analogous scheme you see daily is a sunrise or sunset.”

Using accent colours (designed to highlight features or change the tone and mood of a space) in a neutral palette can stop a space from feeling overwhelming. If you want a more decadent scheme with bolder colours, your imagination is your only limit.

How is this broken down? A popular formula uses

60% Neutral base: walls, large furniture, rugs
30% Secondary colour: accent walls, chairs, window treatments, throws
10% Accent colour: cushions, artwork, vases

And when it comes to your radiator, you can choose to blend it seamlessly into the palette, or become a standout feature within your space.

“White isn’t just white either. Take your time to match your white radiators with your base colour – there are so many variations. If you’d like to keep things neutral but add interest, choose a radiator that is naturally tactile to the touch.”

Stand out with bold monochromes

Monochrome is usually thought of as simply black and white, and while it’s the most popular combination, it’s actually far more versatile. Monochromatic schemes are formed of three shades, tones or tints of one base colour, creating a sleek and luxurious look.

Pantone’s Colour of the Year 2025, Mocha Mousse, or Little Greene’s Affogato and Mochi are great starting points to explore a monochrome mood for your space. Pantone described their Mocha Mousse shade as “a soothing colour of soft brown and thoughtful indulgence.”

If you’re struggling to visualise the scene, think “hotel luxe”, a taupe monochromatic scheme combined with rich tactile fabrics such as suede, velvet and leather.

Caroline says:
“In a monochrome scheme, the details and accessories really count. A radiator can elevate the look, and tall Tuba Steel Column radiator with satin nickel thermostatic valves work beautifully in this type of scheme.”

Let’s talk triadic colour schemes

Triadic schemes use three colours evenly spaced on the wheel, providing a vibrant, high-contrast effect, often with one focus colour and two playing supporting roles.

Caroline says:
“Triadic creates a playful, energising scheme. I love a green, yellow and blue combination. But it works equally well dialled down into pastels for a calmer feel.”

Our hot take: radiator colour combinations

Red hot for winter

Be brave and bold this winter with a statement, jewel-inspired triadic palette using spicy red, royal blue and a pop of butter yellow. We love the idea of incorporating a bright red RT25 radiator, or for period charm with a twist, the Mercury 4 with antique brass valves.

You don’t have to go wall-to-wall with the same shade of yellow to create a sunrise or sunset mood in your space.

Caroline says:
“Selecting pared-down shades of these colours can be a great way to pull off a design using the analogous rule. A neutral base with butter yellow accent chairs and spicy orange accessories will create a warm, cosy space. You might prefer to keep things brighter and lighter with a neutral background and a pop of yellow. Choosing a designer radiator can add interest and colour to make a statement – Oni in Melon Yellow is a great example.”

Green isn’t only bang on trend, but it’s also versatile and loved for its calming, soothing properties.

Caroline says:
“There’s a green for every room, north, south, east or west facing. From soft pastel schemes using pink, aqua and mint green in a triadic theme, to deep jewel tones and green-on-green schemes. We’ve had a lot of enquiries for moss green and deep forest green radiators. Darker greens pair beautifully with natural, tactile materials, velvet and wood seem to be quite a theme.”

Looking for contrast? Try teaming warm green with burnt terracotta or deep burgundy red. We love the Max radiator with corner TRV valves for a high-class, green-on-green scheme.

Nature’s opulent blues

From the coolest pastels to deep jewel-like hues, blue can create a peaceful, reviving or dramatic theme.

Caroline says:
“Rather than drawing from the cool end of nature’s spectrum, consider her opulent, luxurious side. Ocean Blue, Dock Blue and dusky blues create a rich, warm and inviting feel for any space. A great combination with deep blue is our Class radiator in Grigio Iceberg, which creates a sleek contrast and a very stylish modern look.”

If you’d prefer your radiator to blend in with the background and wall colour, Rosy Max paired with either black or chrome valves is a subtle choice.

This colourway has notes of richness. Think warm, earthy autumn tones: spiced cocoa brown, burnt terracotta, moss green, deep burgundy reds and aubergine, all paired with textures that beg to be touched.

Caroline says:
“There are so many options to choose from. We loved a customer’s recent natural approach using steel column radiators in a tactile terra finish for a soothing take. But if you’re looking for a statement, try a textured Horseshoe radiator in Old Bronze effect, available in both horizontal and vertical.”

Don’t forget the valves

It’s easy to get pre-occupied with wall colours and radiator finishes, but the valves are what truly complete the look.

Caroline explains:
“A beautiful designer radiator with plain white valves just won’t do it justice. Take your time choosing – you’ll be so pleased you did.

We have thousands of radiator colours and finishes to explore, and a carefully chosen valve can make all the difference, either helping your radiator to blend seamlessly into the mood, or create an eye-catching conversation piece.
