I scored 7 pretty expected for my age, and being female.

I wonder how important it is to be able to see colors these days.

Red light, green light sight is important, stop signs have shape, at least in the US, but it doesn't make them stand out as much.  If you paint for a living ie cars, houses, etc..., color differentiation could be pretty important, also a dentist that can not see the differences in shades could make very discernible differences in matching tooth epoxies.  

I figure red is the light on top and green is the light on bottom.

Good point about the painters and dentists, but for most of us, color isn't that important.

That was kind of fun.  It's like doing a puzzle.  I think the only issue is that I see different colors with my right eye versus my left one.  I got a 4.  Not sure what that means.  It says best score for my range is 0, worst is 1520.

Gregory, that is a great number, the lower the better :)

Yeah, 4 is excellent. You are a master of color!!
