that was my theory. blue light carries far. red does tend to scatter. I believe thats why the sky is blue.
which brings me back to filters?
if it truly is a wavelegnth thing, then would the proper polarizer allow less of the red light thru, while still allowing the other colors on a narrower wavelength to pass unobstructed?
sorta like the screen on a microwave door.
