Some white LEDs are blue with a fluorescent material in the package to
convert the blue light into an approximation of white. The
fluorescent material degrades with time.

On white or blue LEDs in an epoxy package, the UV causes the epoxy to
turn dark and yellow with age. The plastic cased ones are more immune
to this.
