how well do the sensors pick up color?

What I'm wondering about the cameras is how big of a deal would ambient light have on what it picks up as a set color? Say at home in what ever setting you are working in, say the correct green is defined at 3.5<x<3.7, or around that range, but in a match for what ever reason due to lighting used there the threshold gets knocked up to say 3.9<x<4.2? it will become hit or miss at times.

I know its kinda specific the ranges, but chances are if not the robot may track anything that could be considered at all greenish in its visual range

I'm wondering if the color sensors and "vision tetras" are another addition to the kit and rules that will be like last year's IR stuff, and cause thousands of hours of peoples' time to be spent trying to make them useful in playing the game, with little success. I guess we'll find out in a few weeks.
