You should know better than I but AFAIK you can use the predefined color spaces but you're certainly not limited to them. The documentation says that you can use ICC profiles for LAB, RGB, BGR, and CMYK color spaces. (To me an ICC profiles is that little file with the icc or icm extension. Is the documentation referring to something else?). And in fact you can do that by specifying the input and output profiles in CONVERSION_PARAMS.

In practice ICC profiles will be RGB so you'd be converting with the profiles in RGB or BGR color spaces.

I have spoken with our developers and they said that you are on the right track.  You'll need to use L_ClrSetConversionParams to specify the source and destination profiles you wish to use.

I apologize for any confusion this caused.
