Where does one get the colored lenses that you guys talk about for use in a Marquee to enhance color from each tube?
Are they hard to install?

They're called color-filtered lenses -- NOT color-corrected, which refers to lens design to avoid chromatic aberration errors. You can get HD144 or HD145's, which are very similar. They have a shorter throw distance than the Marquee's HD-8b's so you either have to move the projector or change to a larger screen.
They're not terribly easy to install, mostly because you have to buy adapters to get them to work in the Marquee. Joust sells adapters to do this -- $399 for the adapters AND a set of lenses. You have to make a fairly minor mechanical mod to the lenses to get them to work with the adapters, but the lenses from Joust are pre-modded and ready to install.

Oh. "Nevermind." 
skypuppy, the colored *lenses* I described are for air-coupled projectors like the 8500.
If you have an LC projector, you don't need colored *lenses*. You need colored *C-elements*, which are part of the optical path but not the lenses themselves. Tinted C-elements are very hard to find these days, and it's a pretty involved process to install them. Not for the faint of heart.
