fluid simulations How to let a fluid sim affect the object and change color

[ashxenon 0]

Was experimenting with the fluid sims and I had an idea to make the fluid affect the object as if it was a paint 

for e.g. if we threw a red paint bucket on the wall it will leave stains behind.

For that you'd use a SOP Solver.
