Now, we get dark gray reflective tape next to black all placed on smoked lexan with bright gray aluminum rectangles behind it.

I sometimes wonder if the FIRST GDC has a single controls/vision programmer left on the committee.

While I'm at it, someone tell the guy doing the prints that measurements for WOOD construction don't go out to the second decimal place. XX.88 or XX.31 are not really valid dimensions for carpentry work.....

The tape is retro-reflective. Attach some bright LED's to your robot to light them up in any color you want, and you can have some very bright colored rectangles be easily seen by the camera at any angle. If you choose something other than white/gray/silver/black, like red or green, it's simple work to extract that color and analyze the rectangles that result.
