We chose the Gray Glace cause it looked blue from a distance. We got the same design in the Mauve color for the basement because the carpet we put down there was that sort of coppery-pink color. It was a WARM color for a cold place! ;o)
When we remodel, we want to make our own concrete countertops, and I want a similar color to what I have now. It is almost a neutral because the blue is somewhat nonsescript, but that's the way I like countertops. I don't want the countertop to be too 'busy' because there's a lot going on in the kitchen anyway!
