Color test on molded plastic parts

#1
Anyone can help me to find GM Specs GMGF001 and GMGT004?
These are for color appearance on molded plastic parts.
I dont have the approved master sample to compare and by naked eye I can see difference on color and gloss but no data to accept or reject recent suspect lots.
I have approved AAR sample but I'm not sure if would be valid to do the comparison of current lots against AAR sample and what delta tolerance to use...
Any advise?
