It is mostly the case. Some of the kits are designed to be more manageable at home--not requiring lab-level controls. But still a little fussier than b&w, no matter what. Personally, I haven't looked into too much, because I am color blind and have a hard time with the printing. I stick to b&w now mainly.

I just traded two Mamiyas for a Hasselblad 503. The Mamiyas are fine, but I have too many systems to feed now.
