i prefer inverted orange.  it works really good in most lighting conditions.

i haven't gotten my gameboy yet, but from the pictures I've seen, cyan with and inverted and biverted screen look really sharp.

to me, yellow and orange bl's are my fav's, just because they are easier on my eyes. more warm, but not hot

Biverted red, pink, yellow, and white are my favourites. Everything else doesn't seem to have good enough contrast or is just painful to look at (which is why I'm not a fan of green).

Oh yeah... Color-psychologically it should be taken into account that blues calm you and reds make you more active/aggressive ... what kind of music do you want to make?

Green is a good idea because the eye can discern more green hues than any other color, I did see a teal one recently that I also really liked which is why I bought a teal backlight that I'll receive shortly. Blue is usually quite hard on the eyes for seeing contrasts.

It really just depends on personal preference and experience. Green seems to be really clear as well, but it also depends on the make of the backlight.

Green inverted + 74hc04 = one of the best imho

Here is a comparison between normal, inverted, followed by biversion.

Take into account colour blindness though when you buy (if that sort of thing affects you), because I've tried out red backlights and found them to be the most difficult to see hands down. Green/blue/white are really bright and clear.

white inverted is def my fav. blue looks nice but the contrast is subdued, same with other colours. i've never biverted before cause i dont swing that way

A red backlight looks really nice too. The whole red/black thing looks good, but it looks best with a DMG. I'm not sure about other devices. As for biversion-inversion, I don't know much about that. All I know is that with experience, the bright red backlight does make everything much easier to see, and is also really useful if you want to use it with a DMG in dark light.

oooh I see. Thanks. Any more suggestions anybody?

Biversion is really your best bet.  Green is pretty clear naturally.  White too.  If you are using LSDJ, you can turn on the invert option after installing inverted polarizing film, and it will have basically the same effect as biversion.

Im new to the modding scene and its been a blast.  Ive done some searching but I cant seem to find a consistent answer.I recently got a blue  asm backlight that was neat but kinda blurry. Anybody know which back light colors have the best contrast and clarity as far as vision? I understand biversion/inversion options are open as well.

Thanks alot guys.
