Have you ever seen a color that just makes you go, huh? It might be a slightly lurid shade that you can’t quite place or a hue that seems to border on the medicinal rather than anything like beautiful. Interior designers, however, are increasingly reaching for these tones to create spaces that feel dynamic.

In our pick of this year’s color trends, shades that spark an emotional reaction are top of the list. These ‘wrong’ colors are having a moment — from saturated pops in an otherwise neutral room to surprising combinations that make you think twice (say hello to yellow and brown). “These awkward colors are what everyone remembers most,” explains Chelsey Cox. “Increasingly, perfectly harmonious palettes are falling flat because everything simply agrees.”

So, what is the 'wrong color' theory — and why does every room need a slightly unorthodox hue that might at first look a little bit, well, ugly? Here's what designers say.

What Is the 'Wrong Color' Theory?

No shade works in a vacuum, so the idea of a ‘wrong’ hue is all about context: what it’s placed beside and how it’s used. “Color never exists on its own,” says interior designer Annie Downing. “Rather than coordinating everything perfectly, which feels boring, this concept means using shades that make you pause, just for a second, because you’ve placed them in curious company.”

The 'wrong color' theory works on this kind of contrast in design — a medicinal green, for example, can suddenly feel energetic beside a neutral or tonal palette. “Avoid making your interior feel too uniform,” say Hugo Vince and Adèle Nourry, co-founders of Atelier HA and the designers of the Paris apartment above. “Adding a lively, unusual color or even one that feels slightly retro can end up feeling surprisingly natural if the overall composition makes it work.”

Looking at shades in isolation can lead to them being dismissed before they’ve even been given a chance. “Color is an exploration, but if you’re narrow-minded, you’ll end up with a very limited palette,” explains interior designer Ghislaine Viñas, who believes in allowing bold shades to bounce off each other. “Strange tones like deep chartreuse, mustard, or gray-ish purple can be very intriguing.”

Decorating with a ‘wrong’ color brings a sense of personality. The visual tension helps a space avoid the trap of becoming too ‘matchy-matchy’ or, even worse, predictable.

“It’s all about the push and pull between the colors in a room,” says Ghislaine Viñas. “There’s an attitude, a chicness that comes from doing something you don’t see very often. It’s daring.”

Born in South Africa, Ghislaine is an award-winning interior designer. She works on residential and commercial projects across the United States and is known for a confident, playful look.

When you reach for an unconventional shade, you’re giving your room permission to be different. “This makes an interior much more interesting, even if it requires a measure of bravery and trust,” explains Leah Ring, founder of the Los Angeles-based studio Another Human. “Surprising color pairings make a space feel much more considered and collected, rather than like somewhere that’s been copied and pasted from a Pinterest board.”

If you want a room that feels unique, this individuality matters. “These awkward colors make a space feel like it’s evolved naturally, rather than designed to fit a certain trend,” agrees Chelsey Cox, co-founder of Chinotto House. “When you walk in, they give your eye somewhere to land and make everything else you’ve got in that space appear richer.”

Balance may be an interior design buzzword, but it matters — ‘wrong’ colors only end up becoming meaningful when they’re a focal point, rather than carried across a whole scheme.

“I usually think of every palette as needing a little bit of sweet, salty, and acid,” says Annie Downing. “When you use comforting colors to ground your space, the unexpected color gets to wake everything up.”

At the helm of her own studio, Annie leads a design team working on high-end residential projects. From fuchsia bedrooms to bright green libraries, her signature is bold color.

Using an unconventional or more confusing color with real confidence helps it to look harmonious, so this is the time to be brave. “Don’t bring in these shades on lots of tiny objects,” instructs Ghislaine Viñas. “If you do, they’ll end up seeming like tiny whispers at an opera!”

“You need to scale the color correctly for it to have the right effect,” the designer explains. “Try a table that doesn’t match your overall palette, and then add in a lamp or a piece of art to echo the wild card effect. I love using a bright, warning-sign red in this way.”

Of course, a wrong color can only ever seem ‘right’ if the other shades, patterns, and materials within the space are working too. “If it starts to dominate, balance it with more understated tones and lighter materials,” advise the Atelier HA design duo. “Pay close attention to how natural light changes the appearance of your space throughout the day, and don’t be afraid to test a wide range of options before making any final decisions.”

Ironically, you may have already ruled out the very color that turns out to be right for your next decorating project. Embracing a shade that might, at first, seem too acidic or even ‘ugly’ is a shortcut to creating a unique space — so maybe there is no wrong color after all.
