However the systemnever caught on as it required a fixed grey card to be recorded in the scenebefore the action, something that rarely happened!
There were also developed at least a couple of control systems for color balance and exposure control through the telecine process. Kodak had theirs, which involved calibration films and the shooting of your aforementioned fixed grey card. Gamma & Density had another system (I believe both of these are from the early to mid-nineties) involving a specific chart as shot by the film camera.
These systems weren't meant to replace the colorist, but rather to give him/her a reference or index to determine absolute exposure values, as feedback for the cinematographer and colorist.
In film capture, there still exists, I believe, the concept of shooting some test footage to determine and/or reassure the DoP and colorist of expectations. I tend to see less of this in digital capture, and wonder if other colorists concur? A good test is always worthwhile, IMHO.
