There are three "suffixes" for Kodak print films: NC, VC, UC. They mean more or less: Normal, Very and Ultra. The C is meant to be either Colour (saturation) or Contrast: two adjacent areas of different hues but of matched values have a higher contrast at high saturation than at low saturation.
There are two categories of speed: slow (160 or 100) and fast (400 or 800). That gives the following combinations
100: UC
160: NC, VC
400: NC, VC, UC
800: no suffix, but I suppose it's got to be like NC
All of these films use T-grain technology, the same you find in T-Max. The 800 was upgraded recently, so it might have some newer tech in it. So all of these are colour T-Maxes, not coulour Tri-Xes. I have no idea if Kodak or anyone else still produces colour film using conventional grains.
