welcome to the party pal...its called Color Management.  there are lots of
tools and tutorials out there.

color management isn't anything new.  What You See Isn't What the Film Saw.
and it usually wasn't anything close to what the LAB thought you saw.

and lets not forget all those clients who looked at the beautifully printed,
color and density corrected portrait and then whines, but it doesn't look
like the proof you showed (washed out and several steps towards some other
color.)

well, now we don't have a lab to deal with it.
