Talked to Barbara at Nordstrom Arden Fair (SOOO sweet!!) tonight about Balenciaga wallets and she said they had two blues - the Cobalt (which i bought) and then one that I thought she called "Galois" or something similar, which she described as a quite dark blue. I can't find this color anywhere on the forum though. Anyone know what this is, or another name for it? Is it the anthracite?
