I have MNH stamps from Italy, half of the gum is white and the other half is light brown, I am curious if someone else has this too and what it means.

It probably means that the stamps were kept in a smoking room

Rather think about the influence of sunlight.

This phenomenon mainly occurs with stamps in very hot countries, see for yourself with stamps Indonesia and Suriname.
