VCT tile color, best solid black and white?

[blinn]

I"m considering VCT for my shop. Armstrong sent me a catalog but it's hard to estimate the color of the actual floor because of variations in the tile. Those that have done black and white checkerboard, what tile did you go with? Armstrong sent me a sample of Chromaspin in Lamp Black and Zinc Oxide. They're not bad but I'd like a truer white if possible.
