Yeah green will be the brightest color you will see at night, although blue/violet are very cool indeed. It comes down to preference so if you would tell me blue/violet or green I can help narrow it down for you. BTW wicked lasers are robust but very overpriced. You don't get a lot of watt/dollar with WL. you're best off making your own with parts from survival laser and DTR. let me know what color you want and I'll send you a few different build parts lists of varying prices and powers
