So I have an exam coming up where I get two sheets of paper as reference, and I want to try and use multiple colors of ink (probably red, green, blue, and maybe yellow if it'll work) to put three to four times the information on the first page, and use the second page as a color filter. I want to know, first off, if it'll work (AFAIK it's one sided, so it will actually be of benefit) if I write with multiple colors and have to layer colors together to filter, say, red and green to see blue, or if the light won't work like that with multiple colors of filter stacked on top of each other. What I was thinking was to buy translucent colored paper, as I'm not sure if cellophane would fly, since the announcement does say paper. Would translucent colored paper work to filter the ink, or would it do pretty much nothing? And would the layering work with multiple colors, or am I off base with that too?

Also, I am not at all concerned by the possibility of the professor chastising me for doing this, as I know him well enough to be certain that he'll see what I've done and bust out laughing, likely complimenting me on it as well.

If any of you have tried this, please let me know.
