The biggest mistake people make in their homes when it comes to paint is not checking the colour on a larger scale in a room, says Dulux Creative Consultant Bree Leech.

"I have had people explain to me they selected a neutral grey in the store and when they painted it at home it looked like it was green or blue," she explains. "Of course, the colour is still the same but it can appear quite differently under warm light such as halogens, compared to the harsh fluorescents or even daylight in the paint store".
