I recently decided to experiment with some of the colored/day blade options I have been seeing offered by some of the other guys. Not wanting to pay the premium most of these go for pre-assembled, I got the parts and made my own. One is what people call a photon blade. It if florescent green polycarbonate the reacts to blue and UV light. The other is trans-red. Both have diffusion film and matching bullet tips. To see what happens to the colors, I tried them with VA, CG, AS, GB, FO, and BR sabers with interesting results. In each pic, the top blade is red, the middle is a standard clear midgrade, and the bottom is the photon blade.
VA: Purple
A couple interesting things here. The red blade makes a deep blood red with the VA LED. The photon makes what I can only describe as a watermelon color; as you will see with the red, red light just passes through the blade and as you will see with the blue, blue light feeds the greed florescent. The result looks yellow but is actually pink or green from different angles.
CG: Green
Not much to tell with green. It shines through the photon blade without much trouble. The ral story is how it almost gets canceled out entirely by the red blade. What you see is a brownish color in the top image and it is very dim.
AS: white
While the red is not very impressive (kind of a faux red LED like you would get with a color disc) the photon blade shines with a bright florescent yellow. The brightness is about the same as through the clear blade, but it picked up the color without diminishing. A yellow color disc will cut the brightness, this blade did not.
GB: Blue
Blue is by far my favorite. The red blade makes a deep purple. It is abit dim but it is something I don;t think I could replicate with a color change driver. The photon blade just eats up this color. I have heard other makers refer to this color as rackghoul green and I can see why. Imagine the color you get with black light reactive yellow green material. Then imagine that color without the black light. That is the core, the outside florescent yellow.
FO: Orange
Orange is not very spectacular. It picks up a bit of the color, yellowing out with the photon and going to slightly deeper hue with the red.
BR: Red

Other notes:
Worth also mentioning is tip illumination. The red blade has practically none. The photon on the other hand is excellent. Anything with blue or white light in it fully illuminates the tip. The material itself glows so it does not need to transmit the light. Red spectrum is about the same as the clear.
