Glancing at some properties for sale locally I was struck by the amount of grey used in colour schemes; widening my search area (you can see I wasn't too busy that afternoon) almost every house was painted grey outside, or inside, or had a grey kitchen, and quite a few had newly installed windows with grey frames. It is a smart neutral that can look good with all sorts of brighter shades, but the almost universal sloshing on of grey paint came as a real surprise. What happens when everyone suddenly gets bored with it? A tin of paint will sort out some schemes, but the windows, kitchens, bathrooms tiled in sombre shades...?
