White Ring Light

[dmitch]

My team has a white ring light up at the shop, but no green one. This is the first year that we are trying to get vision targeting working, so I was planning on just using the 2013 vision sample program and tweaking as little as possible. If we are using a white ring light, would changing the value of VALUE (HSV) so that it is a very high number, say 240-250, work to track the white rectangle that we will get? As I understood the vision processing paper, white is simply a very high value number.

I have also done some extensive testing on Microsoft Word with colored squares to see what range of values will return a "white" square. 240 - 250 is all pretty white.

Or, would we be better off getting some green LEDs and using those?
