What are complementary colours?

Complementary colours are the shades that sit across from each other on the colour wheel, such as blue and orange, red and green, or purple and yellow.

 

These strong contrasts can make an impact in any space, but you can also pair muted variations of these colours for a more understated look. Read on to find the perfect complementary pairing for your home.

What is the complementary colour of blue? 

Orange is the complementary colour of blue. Varying the tone of one of these colours (e.g. going a shade darker) can create a more subtle, sophisticated contrast.

Our smoky blue-green Deep Sea pairs effortlessly with this vibrant orange sofa, as the muted blue softens the intensity of the orange. Perfect for a bold look that isn’t overwhelming. Similarly, this front door has been painted in our dark and moody Evening Blue, contrasting beautifully with the bright orange brickwork.

What is the complementary colour of red? 

Green is red’s complementary colour. The two pair well together as a soothing, natural green can instantly offset a vibrant, fiery red. However, it’s best to keep the shades on the dusky side to avoid Christmas vibes.

A classic terracotta like Siena or a weathered red like Faded Ember is the perfect companion to rich olive or sage green decor. You could also incorporate a pink-toned neutral like Sweet Nothing to the scheme to balance a rich red and green palette.

What is the complementary colour of purple? 

Purple’s complementary colour is yellow. Purple and yellow is a stunning combination, especially in pastel form, as it creates a gentle, yet cheery contrast.

The warmth of sunshine yellow Lemon Jelly pairs well with the delicate coolness of Violet Macaroon. Perfect for playful kids’ rooms.

 

Add a summery vibe to gardens with our dusky, pink-purple Lilac Wine. Add pops of yellow with outdoor furniture or cushions to complete this soft yet joyful look.

Alternative pairings

Pink and green

Red and green are considered true complementary colours. However, pink and green also look great together too, as pink is simply a lighter tone of red. Try pairing vibrant, orange-toned Coral with deep Greencroft for a striking contrast. Alternatively, our warm, yellow-toned pink Eleanor pairs beautifully with a dark, earthy green for a softer look.

Blue and yellow

Blue and yellow are not direct complementary colours, but are often paired together to create a bold, high-contrast look. An intense dark blue such as Cobalt or Evening Blue looks striking when paired with our mustard yellow Dijon, creating a visually pleasing contrast of warm and cool.

Orange and green

Although orange and green are not directly opposite each other on the colour wheel, they still create a bold contrast, as orange is a close match to red. We recommend pairing warm dusky orange Cinnamon with an earthy green like Bramwell for a sun-kissed, retro look. Our green Limewash No. 482 looks great with classic terracotta Siena.
