    How to compute the ColorMatrix?


      What's the preferred way to compute the ColorMatrix of a new camera?

      Is it possible to compute the ColorMatrix from the ForwardMatrix?

      It seems that the ColorMatrix can be computed from the ForwardMatrix using the following formula:


      CM = WB * FM^{-1} * MW^{-1}



      - WB is the camera neutral values as a diagonal matrix

      - FM is the forward matrix

      - MW is the chromatic adaptation matrix


      I tried this formula on some color profiles made by Adobe and compared with the existing ColorMatrix.

      However, this formula yields a different result than the one existing in the profiles.


      What am I doing wrong?
