We should think about rooms in terms of mood and how they link together. Depending on the scale of the project, I often prefer to use just one colour. If you have skirtings and cornices, you can paint them with the wall colour for a neater, more modern look. But here’s a tip. Before making any decisions, buy a roll of the heaviest gauge wall lining paper from a hardware shop, organise your paint samples and brushes, drink your cocktails and paint the largest panels you can. The next day tape the painted panels across the space in strategic places; opposite windows, in murky corners behind where the sofa or TV might go, and leave them there for a day or so. Only then will you get a realistic sense of how things will actually look. And with so many fabulous options of paint on the market, be courageous — you can always paint over it.
