No no no. You are just fine. As long as the camera tracks it doesnt matter, and as Alan said the GUI screen is backwards. The only color we can track reliably is red. Though we always illuminate the target with a work light, so that may be why. It definetly has to do with having yellow walls, blue tables, and lights that the camera seems to think are green... It is actually kind of fun to play with the robot and watch to see which part of the wall it goes to when we tell it to track yellow.
