12. Red wine
Copy the water material and name it ‘red
wine’. Change the fog color to a saturated
red, and turn down the multiplier to 0.05.
This will tint refractions red. Apply the
wine material to the water. Render to see
the effect.
Experiment with different colors and multi-
pliers to create other liquids too.
Of course you can do the same thing with
the glass material, to create a colored glass.
