Thanks for the tip! It makes sense to make the actual liquid itself the
color and not just the skin around the outside. The reason I did it that way
was for speed, really; I find interior media to really slow down my
renderings and I like to do a lot of animation with motion blurs so I throw
out a lot of frames. However, for a still-shot, I think Chris is definitely
right here -- it'll make the light interact with the coffee better.
