There are also a total of 6 spines for each lamp shade. The interior of the shade may have some darkening - hard to tell with this color - but assuming they are possibly 40+ years old (or older) I would think it is just a natural darkening from exposure to the old lightbulbs, natural sunlight and other elements.
