Are there color IR films, or is that a video imaging system I'm thinking
about?
The only one I know of is Kodak's EIR, a chrome film, and is IR sensitive
from 700-900 nanometers. It can be shot EI200 and processed E-6 with
greater saturation, contrast and "false" colors, or EI100 and processed
AR-5 for color accuarcy (compared to its predecessor). The EI ratings are
starting points.
Salty stuff, B&H sells it for about $21.50 per 36-exp roll. As with any
other IR film, care in storage, loading, unloading, handling and processing
is essential. Loading and unloading must be done in absolute
darkness. Even if you have it processed E-6, great care must be taken
regarding whatever E-6 machine is used! Most of them have sensors that
emit IR. They must be turned off for processing this film. A "Google"
search can tell you who does the AR-5 processing.

For IR photography information in general, there is a wealth of it on W.J.
