Alan is correct. The human visual system is most sensitive to green and acuity is best in the green portion of the light spectrum. Information extraction and acuity is actually worse in the blue part of the spectrum due to refractive and scattering phenomena in the eye. I won't go into details here and waste everyone's time. Acuity is not very good in the red part of the spectrum as well despite its use to protect night vision. Green lights are now gaining favor as a trade-off between acuity and protecting night vision in cockpits (I was a military pilot and now an active civilian pilot). I worked for four decades in research in part on human factors engineering projects dealing with visual perception and biometrics with regard to problems such as this as well as developing "visual noise" reduction algorithms and predictions oriented toward the cockpit environment as well as other visual systems/environments. I have been most surprised when I see or read about the selection of blue displays as you would guess. Sorry if this not totally Elecraft related but I guess it could be in a stretch.
