Natural fabrics (cotton, etc) responds to bleach & dyes to change colors.
Is there any parallel for nylon (such as a nylon backpack)? Is there any way
to change color of this material?
Thanks,

Well, you could always dye it a different colour - assuming that it's not
black to start with. The trouble with synthetics is that they don't take a
home dye very strongly, it's always a pale modification. Also it will vary
with the synthetic used. Is it really Nylon (IIRC a DuPont trade name for a
polyamide fibre)? - or some nylon like material. If it is Nylon, don't let
it see any acid (it will dissolve...)

Nylon is normally dyed with acid dyes vs. the mordant dyes used for
cotton. The cotton dyes do not work well and I am not sure of
availability of acid dyes to the general public. Acid dyes attach
themselves to the nylon amine end groups.
Chlorine bleach will damage nylon but you might be able to do something
with a peroxide bleach as evidenced here:
