I scored 80 on my CRT, but 0 on my LCD. Obviously the monitor is a very determining factor. So either you re a bit weaker in the greens, either it's your monitor that is. I would bet on the second possibility.

I scored 7 on my macbook, also having problems with greens.

The human eye is usually able to distinguish more shades of green than any other color -- think hunters in forested areas. Perhaps this is changing as more people stare at their monitors all day or bask in the CRT blue. Also more people are near sighted these days.

blue is where humans suck. if you've ever tried calibrating your monitor, you'll know. the hue is blue green so no surprises there.
