Should I add colors to my parts?

My Cad manager recently sent the following rule out to the group:Color components as close to real (MFG.) color as possiblewithout using system colors, but do not color components if notnecessary.

I work with large complex assemblies and have always colored myparts so that I can tell them apart in the assembly, especiallywhen I have very similar parts or configurations of parts, usingconfiguration specific colors. Is there a valid argument for notcoloring parts?SolidworksGeneral
