I like red, but have hunted with white for a lot of years. Red seams to let people get away with a lot more on spooking critters and it helps keep a hunters night vision. A lot of hunters blame a lot of stuff that goes wrong on the light for spooking predators but it is usualy some thing else. I do know for me going from red on a stand to white light they do not stick around long. Like Bigben said, stick to the same color light on a stand. But I would stick with red light, those red eyes show up a lot better with red light and a lot farther for me then white. That has helped me get ready for the shot a lot earler. White light, I just have a harder time picking up the critter eyes as early on a stand. But maybe I just have old eyes and can not see as good. But I do not think so. :-)
Green light I have not messed with so I will not say much othere then green does not reflect there eyes good for me.
But your idea might have some merit to it. But how would you ever know they would not have come into red.
