10 Simple Room Colour Design Ideas: Personal Experiences & Expert Tips for Small Spaces

Over the past decade as an interior designer, I've seen room colour design trends shift from bold feature walls to calming, minimal palettes. In small spaces, I've learned that colour isn't just decoration – it's a tool to expand, brighten, and define a room. Small spaces can spark big creativity, and today I'm sharing 10 simple room colour design ideas I've tested in real projects, supported by both personal anecdotes and expert advice.

Cons: Can feel bland if there’s no texture or accent colours.

Tip: Layer with natural fabrics and rugs for depth, similar to minimalist kitchen storage design principles where functionality meets style.
