lighting for augmented vision WAS: [Re: SV-3 review: super-bright]

I remember back when Apple IIe's standardly came with
monochrome green screens.  There was also monochrome
"amber" screens for people who used them long hours
(to ease the eyes).  I guess because eyes are so
sensitive to green light, green light was too
strong/bright?

Anyway, for an augmented display, I expect green to be
good for bright lighting and amber(golden
brown/yellow), dark green, or red is good for night. 
My augmented display is not assembled yet - but these
are my first initial guesses.

I'd like to hear some input on this from someone who
has a color augmented display working.
