Maybe because one is yellow?

Mine are on craftsman tools, which are not yellow.

I have an Xcelite nutdriver that is red and a Craftsman screwdriver that is
clear with red stripes on it. Both of them have a white dust like material
on them. This is the same stuff that has been called 'mold'. It is not
mold, the plastic going bad.
