There are some apps like "screen adjuster free" where you can play with the RGB colors of your screen and may be able to slightly compensate for a screen color that you don't like. I dunno about the G4, sometimes I look at it and it's fine, other times I think the color is too warm or cool on mine too. It's just hard to tell between a computer monitor, G2 that I still use, and G4, as they all end up looking different.
