How to view different phase in paraview in different colors
 

Good Evening,

I am trying to simulate the interaction of two different phase, say, oil and water. Acturally, I drop the oil into water surface, I want to view how the oil spread on the surface of the water. However, I am stuck with how to view the phenomena in different color. After trying all the method I can think of, I still can't properly different them.

Does anyone know how to view them in different color. My simulation is like below. The droplet is consist of Oil on top of a water base.

Any help would be appreciated!
