I have a Pearl Lexington, last summer I used it almost everyday (out in the sun even) so I didn't bother to store it in it's dustbag when I didn't use it. At the time I didn't even know about the discoloration (it was my first lv). Today it isn't as snow-white as it used to be when I just got it but I still think it looks great. It's kind of light creme-white. I'm not at home at the moment but if you want to, I can try to take a picture of it tomorrow.
