I just bought a new City, Blue Layette, 2 days ago and it's my first Bbag. After been reading more about care and maintenance, I learn that light blue color, like sky blue, seems to fade and turn yellow easily. Fading is not such a problem for me because I think it's natural when you use it for a while. But turning yellow? I really like this color but I don't know how would I response when it turn yellow. What should I do? Should I exchange to other colors that not in blue family? Or should I just keep it and test it out if this so gorgeous color will turn yellow? Thanks.
