I don't think its dyed. I think its just the clay its made out of. We use a regular non clumping clay litter at work, and usually kittens and problem cats feel the need to dump their water, then walk in the litter and back out around the cage... leaving a thick grey mess.
I would think it isn't harmful for them to lick it off their paws... but I don't know for sure.
