Red is one of the most powerful colours in interior design, commanding attention, evoking strong emotions, and adding warmth to any space. Used throughout history in art, fashion, and decor, red has a versatility that allows it to be both a bold statement and a subtle accent. Whether through deep crimson walls or a pop of cherry in accessories, the colour red can transform interiors dramatically. This article explores the aesthetic, practical, and psychological aspects of red in design, explains the 'Unexpected Red Theory,' and details five different tints and shades of red that can be used effectively in interiors.
The Unexpected Red Theory
The concept of the 'Unexpected Red Theory' was coined by TikTokker Taylor Migliazzo Simon. Taylor says, “The unexpected red theory is basically adding anything that’s red–big or small–to a room where it doesn’t match at all, and it automatically looks better.”
With many of today’s interiors virtually void of colour, we could assume that any hue may have the same effect if thrown into a strictly white or neutral space.
But we’d probably be wrong.
The Unexpected Red Theory works because red has specific qualities that are not found all the way around the colour wheel.
While red isn’t the most visible colour (this honour belongs to a bright yellow-green), it is the best hue for catching our attention. Stop signs and red lights, fire engines, and flashing lights are all coloured red for a reason – it’s a natural warning signal that snaps us to attention.
With its eye-catching qualities, red disrupts predictability – especially when placed in an unexpected spot.
And when red has our attention, its physiological effects kick in. Studies have found that exposure to red light increases blood pressure, respiratory rate, skin conductance and eye blinking; in other words, it creates arousal – a physiological measure of excitement.
‘The Aesthetics of Joy’ author, Ingrid Fetell Lee, explains it best:
"When we’re in a high arousal state, we’re more alert and more attuned to information coming in from our senses, which can be pleasant or unpleasant depending on the content. In a beautifully designed interior, it makes sense that ‘unexpected red’ would feel more exciting than agitating."
As designers, we can use this principle to introduce a bold yet controlled contrast that energises a space without overwhelming it.
Adelaide’s Jessie Stevens (SpaceCraft Joinery) applied a bold red beautifully in this striking, retro-inspired kitchen. With just the right amount of design restraint, she utilised Laminex Pillarbox to infuse a vibrant vibe into the space.
From grand historical interiors to contemporary minimalist designs, red has been a key player in interior aesthetics. The colour is often associated with luxury, passion, and power. Depending on the shade and application, red can create various moods:
Bold and dramatic: Deep reds, such as burgundy and crimson, can bring a sense of grandeur and sophistication. They’re often used in traditional or opulent settings.
Melbourne designer Olivia Cirocco (GIA Renovations) demonstrated this perfectly in this stunning bathroom. Sitting atop an opulent Calcutta Viola vanity, the deep red basins immediately draw your attention.
Warm and inviting: Earthy reds, like terracotta and rust, infuse warmth into a space, making them ideal for cozy living rooms and kitchens.
Playful and energetic: Bright reds, such as cherry or scarlet, inject vibrancy and can work well in creative and social spaces.
Subtle and romantic: Softer reds, like rose or blush, provide a gentle warmth and work beautifully in bedrooms and intimate spaces.
How to incorporate ‘unexpected red’ in your kitchen or bathroom designs
If you’re inspired to try adding some ‘unexpected red’ into your next kitchen or bathroom design, here are some ideas to get you started:
- Help your client find the perfect painting to bring red into the space (see below).
- Add a small patch of red to the cabinetry in an unexpected place, like the rear panel of a cabinet.
- Paint a door or door frame in red.
- Add a red shade to a lamp and give it a dedicated home in the kitchen or master suite.
- Find some striking red coffee cups to display in a dedicated coffee zone.
Melbourne's Dylan Duman (Mint Kitchen Group) designed this gorgeous kitchen. The neutral palette is given a boost by the client’s spectacular painting, adding just the right amount of red energy to the otherwise tranquil space.
Have you tried the “unexpected red theory” in your space? How has it worked for you?
While red is a powerful design tool, it must be used strategically to maintain balance within a space. Here are some practical considerations:
Scale and Proportion: A room painted entirely in red can feel a tad too intense, so it’s often best used as an accent colour. Red feature walls, furniture pieces, or accessories can provide a striking effect without dominating the space.
Pairing with Other Colours: Red pairs well with a range of hues. It creates a bold contrast with white or black, feels warm and natural with neutrals, and can be softened by pinks and muted tones.
Lighting Influence: Lighting influences the intensity of red. Natural light can enhance its warmth, while artificial lighting may alter the tone. Therefore, it's crucial to test red shades under various lighting conditions before finalising a colour scheme.
Texture and Finish: Glossy red surfaces can appear modern and sleek, while matte or textured finishes provide a more subdued and sophisticated effect. Take into account the material: Deep red velvet radiates luxury, whereas a rustic red brick wall contributes industrial charm.
Function of the Room: Red is energising, making it a great choice for social spaces like dining rooms and lounges. However, it may not be suitable for areas needing a sense of calm, like bedrooms, unless used in softer tones, as an accent, or as an 'Unexpected Red Theory' surprise.
Red is a dynamic and versatile colour that can add depth, energy, and warmth to any interior. The 'Unexpected Red Theory' highlights its ability to create an element of surprise and sophistication in design. Whether through bold crimson walls, earthy terracotta tiles, or a small pop of cherry red, this powerful hue has a place in every decor style. By understanding its aesthetic, practical, and psychological effects, you can harness red’s full potential to create stunning, balanced and surprising interiors.
