I recently saw an Active Self Protection video that convinced me to put some sort of optic on my PPQ, so I was talking with a friend about it today. He said he can’t use red dots or green dots because of his severe color blindness.
What sort of optics are there that don’t use red or green? Is there one that’s blue? I am partially color blind, not anywhere near as bad off as my friend, but I’ve always thought I’d have an easier time seeing a blue reticle than red or green.
