I see that Surefire makes different color filters for some of there lights. I am wondering what they do and what the different colors do better than each other?
Thanks

I have a red one so it doesn't ruin my night vision when I patrol around the house plus it's good for map reading or looking at Playboy mags in the dark.    

"The FM66 Blue Filter produces a smooth beam of blue light. Hunters use the blue filter to track wounded game at night because blood stands out more distinctly against foliage when viewed under blue light. The filter is also useful for close range, non-tactical applications - such as map reading -- as map reading."  Quoted off of the Surefire site.
