If you knew anything about wave propagation and principles -- you would understand that ANYTHING put infront of a light source will diminish the light output. I don't care what color it is -- be it yellow, green, orange, "light urple", or even clear. The more layers it has to pass through is going to keep it from being at it's full capacity.
Hey, it's up to you ultimately. I don't mess with that shit. I hope if you do get them, you are made to take them off, personally.
