The color of granite in the photo at the top of the page at CountertopSpecialty.com and also seen at our Stone Care Center is Gris Conquistador. 

However, just FYI... when shopping for granite or any stone it's nearly pointless to shop by name of the color. Because natural stone is so unique and because there are over 2500 granite colors, there can be a lot of variation within any one variety/color such that you may find a Gris Conquistador slab in your local warehouse that looks very different. 

Or you may find another stone named say, "Gray Pearl" or "Alaska White" or "Bianco Antico" that looks very similar. 

It will certainly get you started to have a short list of granite color names to begin your search, but in the end, you really just need to go to a stone warehouse and pick out a granite slab that you like regardless of the name. 

But I do appreciate your taste... the granite countertop in the photo is a lovely color/pattern!
