You can have things deposited from the smoke (think about the residue on barbecues, chimneys and things around heavy smokers). Probably this is what you're seeing.

I've had white silicone discolor, pale pink, too. I'd say it's safe.
Note that you need to be very careful to not have the toy catch fire if it isn't silicone. I tested one TPR piece just to see what happened and they are quite flammable and difficult to put out.
