[SML] Blue lighting, somewhat OT.

[Dan Sheehan]

Magenta is Magic.

Snip the linear spectrum band near where infrared becomes visible red and
near where blue becomes invisible ultraviolet.

There is no Magenta.
 It does not physically exist as a monochromatic color.

Roll up that snipped spectrum to make a Color Wheel,
 so the near-infrared end blends with the near-ultraviolet other end.

Magenta is in that gap / splice area.

It's an exciting color, difficult for some tasks (like reading),
and can be headache-inducing,
 because  the human eye senses and focuses red differently from blue,
and the brain sometimes has difficulty processing the mixed signals.

Oh, and it's one of my favorite colors !
