When you are in a situation where you cannot use white light from a tactical perspective, our red and green mix will outperform blue light on multiple levels.
First, blue light is hard on your eyes – when you work under blue light then turn it off or look away into darkness your vision will take a significant time to adjust – more so than with our a mix of red and green light.
Second, blue light creates a much more noticeable signature to the naked eye at distance than does a mix of red and green light – someone looking at you operating under blue light will see you easier than if you were to operate under a mix of red and green light at the same distance, darkness level, viewing angle, etc.
Finally, blue light makes most colored liquids (including blood) appear very dark or black to the eye. This greatly inhibits one from being able to distinguish the type of liquid they are observing with blue light – especially in a situation where multiple liquids could be present. A mix of red and green light allows you to clearly distinguish blood from other liquids – giving you the ability to assess the situation and take the appropriate action much faster.
