Paint pots

I would love to see a version of throwable paint as a way to counter invisibility. I believe it can best be done on a brewing stand by creating an awkward potion and then adding whatever color dye as the next ingredient, and finally, using gunpowder to make it a splash potion. Aim would have to be considered when throwing the pot at someone. It would last for as long as it takes for someone to jump in water to wash it off. It would remain even after invisibility wears off. This could be useful for proving someone was the one that was splashed, unless they washed off first. And perhaps even rain or snow could wash it off.
