for the new floor. The cabinetry will be high gloss in BM snowfall. there will be one island with the sink in a dark stained walnut. There is a LaCanche Cluny in Anthracite in the traditional but the color is a bit blacker/with tinges of grey and dark blue http://www.frenchranges.com/your_colors.shtml

I am not sure of the counter top color. The material will be one of the quartze type: silestone, Cambria, Ceasar stone. What color would you chose? Would you go dark or white? there is Piatra grey in Cesar stone and a Fieldstone in Cambria...white, ? I am kind of stumped.
Please lend me your designer eye
