|Is colour ir available in colour print and slide emulsions?

As far as I know (and keeping open the possibility that Rich may know
a lot more than I do), the only color infrared emulsion available is
Kodak's EIR (Ektachrome InfraRed), which is a slide film.  If you
haven't tried it, hold off until you can get the new version that can
be processed in E-6 chemistry.  (Present stocks require the obsolete
E-4 process, which can be a major bother and a major expense.)

Normally, it is processed only as slide film.  Its colors are so
non-real that you simply have to use the material to learn about it.
Start with a deep yellow filter.  Other filters--generally in the
yellow-red-orange range--give results that some photographers like.
Personally, I prefer the results with the recommended Wratten 12
("minus blue") filter, which is yellow to the eye but yields somewhat
different results by comparison to a "normal" yellow filter.

It's a wild world out there, as seen by EIR.
