I just got an Anthracite RH City. I have a GH Work that I love but I also wanted an RH City in the same color for more casual days. Much to my surprise, the two bags are a different color! Same tone but my Work is much more of a charcoal grey with blue undertones, whereas the City is much much darker; almost black color with blue in it. Here's some pics to show you how much Bbags can vary from one bag to another in both color and leather.
