Not positive - but from what I've been told different stores/suppliers call it different names sometimes.. I heard this from the "marble slab" guy when we went to pick ours out - he said well.. "Home Depot calls it xyz"..

I was wondering how someone was going to answer this. My , one of my wives, once had me look at 30 paint chips and said which Colour did I like, I said they all looked white to me.
