Vision related things

The color shouldnt really matter that much, I mean we use blue and we originally had green LEDs. There was no real reason we switched colors,however the green leds are far more common. The only thing with the blue leds(and probably red too) were when we went to do vision calibration we got the castle lights in our image but through code I was able to remove them for vision tracking. You can see them on our bot: https://youtu.be/8lUen2X_a_M

Our team uses IR to track the targets. We use a IR camera, you can make one by removing the IR filter and putting a light filter in place of it, and just have IR leds. It gives use a black and white image but makes it so we see just the targets, but lights are a problem but we've fixed that at competition.
