Now how to explain the mixed limbs Chewbacca below?

Simply. . Different pigments in the paint (which in this case is mixed through the plastic) are expected to have a different vulnerability towards light induced and/or chemical degradation, two processes which can result in a color shift during time (here brown to green as the red pigment decays). Assuming the same light exposure during time (as is the case in the MOC), the extent to which a pigment is prone to degradation depends on the chemical structure of the pigment and the direct chemical ''environment'' which can accelerate reactions and therefore makes things worse. Think for instance about the concentration of neighboring plastifiers, or flame retardants (producing free radicals, chemically highly reactive species) within the plastic. Different batches of plastic might have slightly different compositions, and therefore the colour shift might process at different speeds.
In case you would mix up the limbs from two different batches (which might be common practice in the Kenner factories) you could end up with the mixed green/brown limbed Chewie.

PLEASE KEEP IN MIND: The same explanation holds for other degraded figures with different coloured limbs. Also be aware that limbs and torsos are made from different plastics and hence may discolour differently in time.
Sometimes you read in threads: "The arms/legs/torso have a different colour compared to the torso/arms/legs, so it can't be degradation." After reading this, you understand it can well be.
