I just bought a Gretchen bag in Slate at NM Last Call today. I fell in love with both the shape of the bag and the color of the bag. I've never seriously considered buying a Kooba before, and I've never read the Kooba board on tPF before. So, I was pretty upset when I came home, searched the board for threads about my new bag, and read all about how everybody's Slate bags are changing color! If the color just darkened a little bit, it wouldn't bother me, but it sounds like people are actually seeing their bags fade to a nasty shade of tan. What should I do? I can take it back to NM, treat the leather with leather protector and see what happens, or just leave the bag as it is and see what happens. Do you think if it hasn't faded yet, maybe it's safe/not defective?
