The duller less bright cards are faded from sitting out on display 99.9% of the time. As an example you won't see it as often in the 61 Topps because they do not fade as easily.
If you have any specific questions or cards I would be glad to help.
EDIT: As a collector of print errors it bothers me a lot and I avoid them only because it is one of my pet peeves.
