As stated in this thread:
http://www.chiefdelphi.com/forums/sh...threadid=32226 , and in the manual:
<R26> No devices or decorations are permitted on the robot that are intended to jam or interfere with the operation of the vision system (i.e. changing robot color to confuse opponent’s vision system).
I think that MOE green is different enough from tetra green that the vision system should know the difference, but I dont know how precise the sensors are.
