I really love the Night leather as well. It's beautiful. I wish I could help you out but this is the first RM leather that I have seen like this. It's different from all the other leathers (IMO). It's not like the glazed leathers (Tangerine, Almond & Espresso etc) , it's not like the glossy leathers (wine, emerald etc) and it's definitely not like the Matte leathers (Elephant, Navy, saddle etc)
Luna Boston calls it "Polished" which I feel accurately describes it. I hope more leathers come out like this. Maybe there is someone else out there who has seen a similar type of RM leather?
