Paint is one of the quickest ways to refresh a space. It’s affordable, forgiving and far less disruptive than replacing furniture or fittings. But when it comes to small rooms, colour choice matters more than you might think. The wrong shade can flatten light, close in walls and make a space feel tighter than it really is. 

While no colour is truly off-limits, certain tones tend to work against compact rooms – especially those with limited natural light. Before you commit to a weekend of painting, here are five colours worth reconsidering, and smarter alternatives that keep small spaces feeling open, calm and intentional.

Cool Grey

Grey has long been a favourite neutral, but in small rooms it can quickly lose its charm. Cooler greys, in particular, highlight shadows and make walls feel dull and lifeless. Instead of reading calm and modern, the space can tip into feeling cold or unfinished.  

Try instead:
Warm greige, soft stone or light taupe. These shades keep the neutrality of grey but add warmth, helping light bounce around the room rather than disappear into corners. 

Black and Charcoal

Dark walls can be dramatic, but in a small space, black and charcoal often swallow light rather than enhance it. Without strong sunlight or clever lighting, these shades make rooms feel boxed in and heavy. 

Try instead:
Deep jewel tones like forest green, inky navy or rich burgundy. They bring depth and mood without draining the room of warmth. These colours feel layered and considered, especially when paired with natural textures like timber or linen. 

Pale, Washed-Out Neutrals

Light colours are often recommended for small rooms, but very pale or muted tones can leave a space feeling flat. In rooms with little daylight, they can read dull rather than airy, making the room feel like an afterthought. 

Try instead:
Saturated mid-tones with personality – think clay, olive or warm sand. Painting walls, trim and doors in the same shade creates a seamless look that reduces visual breaks and allows the eye to rest, making the room feel larger. 

Deep Blue

Deep blue is calming and elegant, but in small or dim rooms it can easily become gloomy. The colour absorbs more light than expected, which can cool the mood too much and make the space feel uninviting.  

Try instead:
Blue with grey or green undertones, or lighter shades like dusty denim or slate. These versions still offer depth while reflecting more light. Balance the colour with warm metals, pale wood and layered lighting for a softer finish. 

Terracotta

Terracotta brings warmth and energy, but its rich pigment can overwhelm a compact room. Because it absorbs light, it often makes walls feel closer, especially in spaces without good airflow or sunshine.  

Try instead:
Peach, coral or soft clay tones. These colours offer the same earthy warmth but reflect more light, helping the room feel brighter and more relaxed. Use terracotta sparingly through décor if you still crave that sunbaked feel. 

In small rooms, consistency is key. Too many contrasting colours break up the space and draw attention to its size. Keeping a tight colour palette, layering textures and choosing finishes with subtle sheen can make even the smallest room feel thoughtful and welcoming. 

When in doubt, always test before committing. Paint a large sample and live with it for a day or two. Light shifts, moods change and a colour that works on a swatch might behave very differently on all four walls. 

Small spaces don’t need safe colours – they need smart ones.
