8 Ways British Designers Use Green Paint to Make Small Rooms Feel Bigger

It’s natural to default to lighter shades in the hope of maximizing light and space. But in reality, they’re often the perfect places to be more confident with deeper colors.

As Rob Abrahams, CEO and cofounder of COAT, explains: “One example is using a deeper olive tone. While this might seem counterintuitive in a small space, it can work incredibly well when done right. Rather than closing the room in, darker shades will actually create a blurring of the outline of the space, which softens the edges and creates the feeling of depth. It’s almost cocoon-like, and can work so well in bedrooms and bathrooms in particular. If you wrap the same colour around the ceiling and woodwork too, it maximizes that feeling.”

If your room is filled with natural light, this is your chance to be playful. Zesty lime greens bring instant energy, while a pop of red adds contrast and lifts the whole scheme.

We asked Andy Greenall, head of design at Paint & Paper Library, for his advice: “By their nature, south-facing rooms are ideal spaces to use bold, vibrant colors; a warm, all-day light source will increase their intensity, providing natural design impact. The punchy-yet-sophisticated ‘Euphorbia’, as seen here, sits perfectly on the green-to-yellow scale, and has been elegantly used alongside tonal tiles, so the layering is achieved by varying texture rather than by varying color.”

As tricky as they can be, tight alcoves and sloped ceilings are the perfect place to go bold—in a controlled way. Rather than trying to hide awkward shapes, a vibrant green helps define them, adding just the right amount of impact. This bathroom is the perfect example of how a single, well-placed hit of color can transform even the tightest layouts.

“We paired these rich-toned green tiles with paler surrounding colors, including a small-scale wallpaper with a warm white base. This allows the green to really pop without feeling overbearing, as it has light and space surrounding it. The color and texture of the green tiles really give the space some depth; it adds another dimension,” says Holly Vaughan, director at Vaughan Design & Development.

If your room feels slightly out of proportion—too tall, too open, or lacking focus—this is where a confident use of color can help. Dipping everything in a vibrant green creates a continuous envelope that visually lowers the height and pulls the space together.

Here, DIY Instagrammer Anne-Laure Lievense has done just that. A contrasting pink sofa adds a hit of energy, bringing a playful, modern edge to an otherwise grounded palette.

“Our living room is quite small, but it has a high ceiling and faces south,” says Lievense. “I wanted to make the space feel cozier and visually bring the ceiling down. That’s why we fully color-drenched the room in the shade Bancha by Farrow & Ball. It doesn’t make the space feel smaller, but definitely cozier—and that’s exactly what we were looking for.”

If your room lacks natural warmth, don’t shy away from color. In north-facing spaces, cooler light can leave neutrals feeling flat, but warmer, yellow-based greens help soften the effect. Used across cabinetry, as seen here, green provides just enough interest to keep the scheme feeling considered, without the need for pattern, adding structure without clutter.

“Greens with blue or gray undertones can make a room feel colder, so it’s best to opt for those with a stronger yellow base to warm the space,” says Tash Bradley, director of interior design at Lick. “In lower light, using the same shade across walls and woodwork creates a cohesive, cocooning effect.”

Here's another striking example of how a well-placed block of color can lift a scheme. A narrow staircase, often overlooked and kept as light as possible, has been drenched in Lichen by Farrow & Ball.

“For the staircase, I introduced a deeper green to contrast with the softer neutrals and draw the eye outward towards the rural countryside view. Blue-toned shades like Lichen create a muted depth that quietly recedes, allowing light and landscape to take centre stage,” says Charlotte Lloyd Owen at Chello Interior Design.

Whether you start softly with sage or go all-in with a deeper, cocooning shade, green proves itself to be far more versatile than traditional neutrals, adding depth, warmth, and personality to even the smallest of spaces.
