Interesting subject.

Red is a good, but only at low wavelengths - around 600 millimicrons.
At higher wavelengths, it is virtually the same as white light.

Better is blue/green (teal) around 525 millimicrons.


I thought it was best to stay away from the peak response of
the rod @ ~500nm. That's why a longer wavelength red 600nm
is good. 525nm is almost at peak rod sensitivity. (?)
