We have just had our kitchen replastered, we are sticking with the original units, that were in the house when we bought it, although not modern practical.
The units are a dark wood colour, the worktop is green, with black flecks (yes green)!! Cant really afford to change at the min, its not overally in your face green.
We have decided to have one row of black tiles, quite big chunky ones, and a grey floor, the walls are going to be an off white to brighten up.
I originally wanted black accessories, kettle, storage jars etc, but do you think this will be too much with dark tiles?
