That's actually a neat idea, color for immediate visual feedback. I
imagine the problem is the colors. What would be sane? I guess three
basic colors and interpolate between them?
low = blue
middle = yellow
high = top

It needs to be rather intuitive. I guess the more colors the less
intuitive it will become. Maybe two are enough.
I wonder which color would best represent 'low' or 'bottom'.
Blue, black?
