Note: If the patch exceeds the limits, it turns black on the dark end of the specturm and turns white on the bright end of the spectrum. Examples: `scale-color green density 0 20` Patches turn one of twenty shades of green. Patches with lower density turn darker green. `scale-color blue energy 20 0` Patches turn one of twenty shades of green. Patches with lower density turn lighter green.
