There isn't really a "right" and "wrong" way...just rules of thumb that
usually work. "Hue" is an artificial way of specifying an attribute of
colors, there is no physical reason for emitting gasses to absorb light
of the opposite hue. The colors being absorbed don't always match the
color being emitted.
Actually, there is a "right" way, but it would require patching POV to
addjust the dynamic range. The beams of light are brighter than the
background, but the background is "white".
