[sdiy] changing colours on banana inputs

[Rude 66]

this may be a weird question, but is there a way to change the colour of a
banana plug input chassis? i've got a whole bunch of white ones, and would
like some to be different colours. paint will probably peel off the plastic
after a while.
would there be any way of changing their colour permanently? chemical bath?
exposure to light, sound, radiation, screaming kids, or toxics? etc.. ;-)
