Well I think i've figured it out. I was looking at the beam with no fog/smoke real close (1 inch) and it's kinda like looking at your tv screen @ 1", you can see each individual RGB 'pixel'. Far off though they all blend together mixing like 1 color. I was just kind of disappointed that on a semi-clear night the beam wasn't more of a yellow or orange -it was kind of a dim gray color. I guess that's normal. I'll have to wait for a foggy night--stupid question tho i guess oh well, back to work :/
I would like to figure out how to mix colors using fiber unless too complicated/ expensive.. probably have to deal with numerical aperature numbers and calculations -things I know nothing about
