Eliminating Color in a Axis Camera

[ThisIsSparta]

At the Midwest regional, we had difficulty with getting constant targets from the Rectangular Target processing VI using a green light setting. We got more consistent results after expanding the values on the "margin" controls, but consistency on the field doesn't seem reliable enough, even after calibrating.Is there a way to eliminate all color but green from the camera? I noticed that the targeting VI does all of it's logic in HSL, and the only way I could think to eliminate all colors but green is to convert to RGB and take out the planes of R/B. Thanks in advance for any help!
