No idea about deer but i know that the military uses red b/c its the lowest visibility at long range. Arent deer colorblind though?
So I would think that it wouldnt matter what color it was, they would just see light and movement and spook.
"War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself."
-John Stewart Mill
