Hi, I'm having a new kitchen diner built it is a relatively large space and I have a colour scheme of Granite grey and matt white. To add colour I have purchased a mustard coloured settee (not in your face bright). Question is, are there any other colours that go well, to add a bit of interest. I intend my kitchen to be quite sterile looking - softened with some large family photographs and house plants, any other ideas i.e. I will buy a few cushions for the settee etc. I really want to avoid clutter as this is a major issue perhaps this is all I need? Just wondering whether I should throw a 3rd colour into the mix or leave it at that.
