Rifle Scopes Red vs Blue

I'm not sure of the context, however, as someone with red/green colorblindness my feeling is that a blue illuminated reticle will provide more contrast on a green background than a red illuminated reticle.
 
The biggest difference is what your eye picks up or what it doesn't pick up. If you have a color deficiency its usually between red-green, and blue-yellow. Best option is to take a color blind test online.
 
I thought Red vs. Blue were internet cartoons made using Halo? :-D

Honestly I think it is what you eye feels most comfortable with.
 
Blue is easier on eye fatigue.

NO way. Blue illumination increases eye strain. Blue is an easy color for the eye to pick up, but it causes blurry vision when concentrating your vision on blue light. Details are very difficult to make out. Don't believe me, try reading blue business signs at night from a distance. They appear blurry as hell.

The reason why US Optics offered a blue reticle, is because the blue illumination produces a lower iR signature, so it is harder for the enemy using night vision to spot a US soldier using a blue reticle. No other reason. Problem is that people confuse intended purpose with performance, and they want to have what the tactical community has. If you shoot in low light conditions, and absolutely need illumination, red does just fine, as does green. Leave the blue for the guys that are getting shot at.

Interesting info. I know from my military days, red was preferred as is has less of a negative impact on your own native night vision.
