I've got a couple theories. If you look at the right side shots, then the loft side shots I posted, you'll see that one side matches the bumper, the other does not. I'm curious if the paint code is wrong. Honestly, I see mismatched bumpers and panels on this color all the time. Always those two shades. The other option would be sun fading, and it's more likely. Although fading usually dulls color, and the duller yellow is the right color. Hmm...
As far as the bumper goes, I think that just comes from time and molestation of the bumper, over time the clips fail, get lost and break especially after repeatedly being taken off.
