Decorating with grey has been a dominant theme in key interior design trends for the past few years, but there are common mistakes many make when using this popular color. We consult interior designers to find out what those are and how to avoid them.

As a timeless neutral with so many different depths of tone, decorating with grey can sometimes feel a little overwhelming, leading to styling mistakes that prevent this popular interior design trend from being as impactful as it could be. Whether following the latest bedroom trends and painting the walls grey or choosing furniture pieces, you have to carefully consider how you use the shade, and if it really works in your space.

We speak to interior designers who all too often see the same mistakes homeowners make when choosing to decorate with grey. So if you're considering incorporating one of the biggest interior paint color trends into your home, here are their dos and don'ts.

The 7 common mistakes to avoid when decorating with grey

"Grey is one of the most versatile colors, yet when decorating interiors, I often see people make mistakes when incorporating it," explains Anne Haimes, Design Director and Founder of Anne Haimes Interiors (opens in new tab). "To help make your grey rooms more welcoming, picking the correct shade, choosing a color palette, and introducing texture are all key."

Here are the pitfalls you need to avoid.

1. Choosing the wrong shade of grey

Let's start at the very beginning of the process: don't make the mistake of choosing the wrong shade entirely – whether, for the paint or furnishings, it's key to get the shade right at the very start.

"Often people don’t realize that there are different tones within any grey color, some pick out a grey paint color with a lilac undertone and don’t realize!" warns Giverny Simm, Design Manager at a bespoke interior design house, Hatch Interiors (opens in new tab). "Resulting in a space that is completely different to how you envisaged it. Above all else, make sure you take into account the light when choosing a grey tone as failure to do so can result in a space that feels drab and dark!"

"A common mistake when decorating with grey is not considering the direction the room faces and how you’d like the space to feel," says Aaron Markwell, COAT’s (opens in new tab) Colour Curator. "Classically north-facing room may benefit from a grey with a warmer undertone or by taking the color darker, to create a cozier cocoon-like vibe."

"I’d recommend choosing greys with a beige undertone to them like COAT’s taupes, Good Intentions (opens in new tab), or Sunday Soul (opens in new tab). If going bold, darker greys with a hint of color can create impact yet maintain warmth like the dusty dark grey-green, Darlington (opens in new tab). If space is flooded with light, maximize the airy feel with more modern, cooler shades. Pale greys like Sweatpants (opens in new tab) is a great alternative to usual whites or classic creams."

2. Exclusively using grey paint

Of course, a fashionable grey is a great choice for a living room paint color or bedroom paint color but the wall color is not the only element to cement a successful grey decorating scheme. 

"The most common mistake we see with introducing grey to a space is defaulting to grey paint," explains Devin Shaffer, Lead Interior Designer at Decorilla (opens in new tab). "Grey works brilliantly as an accent color and meshes with a variety of colors, allowing it to bring visual interest when applied to decor elements such as throws, pillows, cabinet colors, etc."

"We love letting other neutral colors such as off-white's and beiges run the show as the wall color – while providing the perfect backdrop for layers upon layers of different shades of greys." Explore the best white paint colors to match the right undertone with the shade of grey you choose.

3. Using the same shade for everything

Even if you have decided on a greyscale decor, it's important to use the whole spectrum of different shades to ensure the room doesn't feel devoid of interest and depth – look for contrasting light and dark greys for different design elements.

“The worst design mistake you can use while incorporating grey, is using the same shade for everything,” warns Zara O’Hare, interior design specialist at Land of Rugs (opens in new tab). “This will make your space look flat and boring.

"Instead, make the most of all the grey shades available. For example, you can use a light grey rug to accent dark grey furniture. This will allow your pieces to pop instead of blending in.

"A large room that gets plenty of light will give you more options and can accommodate darker, cooler tones of grey," explains Anna. "On the other hand, a small, dimly lit room will need to rely on lighter shades with a hint of yellow to appear warmer."

Anne continues, "you should also consider existing features you already have. If you have warm finishes, such as wooden beams or cream windowsills, you can offset this with cool shades with a blue undertone, while stark white or other cool-toned features may need a warmer shade of grey."

4. Not picking one dominant grey tone

While mixing shades of grey can be glorious,  another common mistake is mixing the wrong depths and tones of greys. "Grey is the new neutral. Take a look at any model home or any home renovation program, grey has become the color hue nearly every designer starts with," explains Badcock Home Furniture &more's (opens in new tab) lead designer, David Horvath. 

"The most common error we see in decorating with grey is layering too many different tones of grey together. One should never equally blend a heather grey with a steel grey and a charcoal grey in the same room. You want to select one grey tone and build around that.

“It may sound obvious, but the single biggest mistake people make when decorating their homes with grey is simply using too much grey. When lots of different shades of grey are used in a single room, it is likely to feel very cold and one-dimensional, which doesn’t make for an exciting and dramatic space. 

“I’d always recommend picking a single shade of grey," advises Amy Wilson, interior designer for 247 Curtains (opens in new tab). "My preference would be for a pale grey with a touch of brown combined with warmer tones such as blush pink, terracotta, or burnt orange. However, if you like the industrial interior style, the yellow and grey look really impactful and contemporary. "

5. Leaving rooms feeling cold with cool-tones

Look to add warmth to any grey color scheme, especially in rooms that lack natural warm light. "Long gone are the flat grey-on-grey rooms that once dominated Instagram," says Anne. "Today, grey rooms must include other tones and colors for a more balanced, sophisticated aesthetic."

"One of the most common mistakes of grey interiors is only using cool-toned shades, which inevitably makes a living room seem cold and uninviting. To avoid this, balance the coolness of grey by complementing it with warmer tones.

"Without the pop of accent colors, your grey room could start to appear uninviting," warn the interior specialists at Living Cozy (opens in new tab). "Adding in some darker, or more vibrant decor and accessories to brighten the room will give the impression that your grey walls are brighter than they initially appear and create an open, inviting space for friends and family."

Anne adds, "Luckily for people who love color, grey provides the perfect base for almost any color palette – though it’s best to avoid pastel shades or primary colors when decorating with grey, or you’ll have too sharp a contrast. Instead, opt for earthy shades that complement it.

"If you love your space bright and bold, try Mediterranean-inspired colors such as warm teal, terracotta, and mustard, which can look stunning when paired with lighter greys."

6. Not layering texture to add depth

Texture in itself is a huge interior design trend to emerge in recent years, as we strive to add interest to neutral schemes without overwhelming spaces with color and pattern – just look at the popular Japandi decor trend, where tactile materials play an integral role.

"A mistake people make with grey is not introducing enough texture to balance out the cooler tones," warns Amy. "As a general rule, grey is much more successful where texture is applied rather than as a flat finish, like with paint. Therefore, I’d recommend using grey sheepskins, grey linen, and voiles for a softer note. Similarly, if you have a large piece of grey furniture, like a sofa, for example, make sure you layer with contrasting textured cushions to soften the block of grey.”

"To create depth and interest, use a variety of tonal grey shades in a mixture of textures," suggests Lou Petersen, Creative Director at Dwell (opens in new tab). 'Such as pairing a dark grey velvet sofa with lighter grey scatter cushions. This will immediately break up the color and stop it from looking two-dimensional." 

Avoid too many metallic touches warns Anne. "Glam can easily look tacky if you’re not careful, particularly when coupled with silver and grey. So unless you love a glitzy home with lots of sparkles, you’ll want to avoid pairing a grey room with anything too shiny." Before going on to suggest, "instead, introduce matte natural textures such as wood, wicker, and wool to help make your space instantly feel more welcoming."

Adding visible softness can also help make your room appear more inviting. Grey linen-finished sofas are having a moment this year, with the relaxed texture helping to create a more calming feel. Additionally, the best blankets and throw pillows in a mix of textures can help make a space more visually appealing while adding softness to a grey sofa or bed."

7. Shying away from bold accent colors

In line with the mistake of making everything grey, there's a fear of adding bold colors to a grey decorating scheme - when in fact a striking contrast can lift the overall look in any room. "Grey needs a highlight," explains International Interior Designer Joanna Wood (opens in new tab). "If everything is grey then the mood is 'down' so give a grey room a really good pop of color." 

“Grey has been fashionable for a long time and is the most misused color we see," says Elaine Penhaul, Director at Lemon & Lime Interiors (opens in new tab). "If you love grey for the walls or woodwork then choose a striking accent color for the room that contrasts to really lift the grey into the realms of exciting decor."

Elaine goes on to suggest, "a fuchsia pink chair in a room with dramatic wall paneling in brooding charcoal grey is amazing. A softer but no less gorgeous scheme could be very pale grey with a teal sofa. Don’t be afraid to go bold with your contrasts.”

"Adding vibrant cushions is a simple and inexpensive way to inject a bold hit of color into a neutral grey sofa," suggests David Harris, Design Director at Andrew Martin (opens in new tab). "Start with the soft base linen colors for your sofa, and then try mixing in the hotter pink cushions for added zing. But, if you’re more reserved in your approach, then opt for the soft powder’s blues and neutrals."

What colors go with grey for decorating?

Grey is the perfect color to accompany any other color; the key to finding what colors go with your decorating scheme lies in finding complimentary color palettes.

"Two of the best things about grey are firstly the range of shades available but also just how suitably it pairs with almost every accent color. Having said that, the key to styling the right grey with the appropriate accent color is knowing what tones work and which might clash," says Zara.

“Pay attention to whether your gray is on the cooler end of the spectrum, or if it’s closer to the greige. If it is a cooler gray it will pair best with white or blue furniture and decor, while greige looks best with warmer woods, brown or taupe.” 

“To create a balanced color scheme, it’s important to consider the composition of colors within the palette, rather than addressing colors individually, " advises Jodie Hatton, Design Manager at Brintons (opens in new tab). "For a dramatic look, pair grey with layers of dark, moody tones like aubergine or midnight blue. If you’d like to incorporate a fresh look, infuse the palette with a lighter, softer shade that glows, like golden yellow or bright green.” 

 Jodie continues “Your home should be a reflection of your personality. The warmth, coolness, saturation, and intensity of color, all create different effects but pop when paired with grey. Consider how each room will be inhabited and experienced and most of all, have fun with color!”

"Those who favor a neutral palette should take inspiration from Japandi, one of the most popular interior trends right now," says Anne. "Though the style leans cool in tone, the inclusion of some warmer, natural materials helps offset the coolness in a stylish way."

Adding color is easily achieved in any room with the simple addition of rugs, throw pillows, drapes, and even artwork.
