enter a store, steal some paint, and throw it everywhere

You would, but the only paint is black and white.

It doesn't appear to have any liquid properties either.
What the forget is going on here?
enter store
buy rock
put rock in inventory
buy useless item
walk to wasteland
drop it to see if it disappears
You combine the both and take a rock you found off the floor.

It shatters into burning material waste the second you leave the store.
You hear footsteps.
