    Why should oil not be clear, almost colorless?

    The oil has to be above the water.

    Dish soap comes in any color. Water can be colored any way.

    We know which one is milk. We know that dish soap is denser than water. We know oil is less dense than all of those. Does not leave at lot of wiggle room.
