Hi there! I am contemplating whether I should get the black and white ombre or the grey and blue ombre for the Lizard Leather for the Classic Box.. I really love the black and white ombre but I saw a post here that it turns yellow.. A part of me says go for the grey and blue but part of me wants the black and white. I want to see others' opinions with these two colours and whether Lizard Skin is really delicate? Any pros? cons? Should I bite the bullet and get an exotic skin? Or better with the box leather?
