 to aid in the biocompatibility evaluation of polymeric medical device components that contain color additives (CAs)[^1]. These assessments can assist device manufacturers by providing instantaneous feedback on whether the presence of CAs or 
 other additives and impurities associated with CAs in a device would require additional justification and/or testing to 
 demonstrate acceptable biological risk.  The output of CHRIS is a conservative margin of safety (MOS = toxicological

 biocompatibility endpoints is necessary for the CA and/or associated impurities.
