My kitchen is similar to the attached, but smaller. The walls are currently taupe, but it needs re-doing, and i'm bored of it's dingyness. My kitchen is north facing.
I've been looking at whites, greys and blues for the walls, but along the way I've found that little greene white lead is not only a great colour match for the cupboards, but also has the most wonderful glow, even in my dingy kitchen. Dulux timeless looked a bit grey in there for example.
I hate painting the kitchen because of all the cutting in. Can cream on cream look contemporary, or will it just look country (which I dont like). Also, there will be no contrast if the walls match the cupboards, can this look good? Or is contrast important?
