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?
