I'll second Alan's endorsement of Anders. Very strong in that one, the Clue is.
I only just now skimmed that page and quickly, but it looks to be a superlative
resource.
And, since the original question is about using a camera as a colorimeter...to
even pretend to start down that path, you're going to need a best-of-breed
camera profile. And, for that, you have basically three options...find one of
the very few people on Earth who can do it for you; dive _very_ deep into the
color science waters; or cling for dear life to Anders's DCamProf. It's not for
the feint-of-heart, but it's the only option I know of short of rolling your
own that at least has the potential to approach the limits of input profiling.

Note that, to realize the full potential, you'll need the camera's spectral
response ("SSF" as Anders calls it). This is something you can measure for
yourself with inexpensive homebrew kit (large spectroscope, etc.) plus a
spectrometer for calibration...but you have to know what you're doing.
