Chewie is supposed to be around 200 years old in the OT. 30 years since Jedi isn't going to mean a heck of lot with that kind of lifespan. I don't see cats or dogs getting gray as they age.
And didn't we have this same discussion about his appearance in ROTS? ;)
My dog started off completely red in color. 13 years later he's almost completely white.
