CFL's with light gel colorization?

Another potentially idiotic newbie question here. :)

I'm doing a very small closet grow, 4 plants - 3 Afghans and 1 generic whatever that came free with my seeds - and I'd read recently that flowering requires warmer (3500k) light. I have 2 150w extended CFL's and 2 100w small ones, all in the "daylight" (5500) spectrum.

Would yellow gel paper filter the lights and give me more of a warm color spectrum for budding? Or would it just block too many lumens? :idea:

Thanks for any and all opinions.

red plastic? jk.. I think the spectrum has to be generated, it cant be mimicked.
Agreed.. has to be generated, only time you'd get away with something like that would be if you were -filtering- (see: removing) specific spectrums from the equation for a reason I couldn't begin to guess at - unless you were doing spectrum testing vs strain response with a solid standard/benchmark to work form.

Okay, I'll accept the group's opinion that this is not the way to go. lol

In regards to this last answer, however, yellow gels DO remove blues, in particular. I've worked a lot on stage prod. crews. That's what gels do, they don't ADD anything - light hue is subtractive. Just like blue-blocker sunglasses are yellow as well - they remove blue. Here's the scope on the particular gel I had in mind.
