I just received a pair of Ranger Edge glasses from Morgan Optical yesterday. Wayne Morgan wanted to be sure the prescription was correct so he made one pair of lens in target orange. This is a custom shade of his and what he recommended. He is now in the process of making me an additional pair of med. yellow lenses and purple.
That is what I tried at my club using non-prescription lenses to get a feel for color. When I asked for orange Wayne suggested his custom target orange. They work great.
However, if you are color blind or sensitive to color variations, these colors may not work for you.
