Try an art supply store that carries Pantone products.  Pantone makes
(or used to make -- I haven't bought any for a while) transparent
plastic sheets that graphic artists use when producing drawings that 
need very evenly colored sections.

Another potential source is a theatre lighting supplies store.  Ask
for the "gels" used on stage lights.  (These probably don't have the
optical quality or the transmission characteristics you need, but
it might be worth a try.)

Finally, if there's an industrial plastics store in your area, they
will probably have colored plexiglass.  In Denver, I'd go to 
"Plasticrafts," a regular haunt of artists, art students, and 
makers of neon signs and custom displays.
