Cie guidelines for coordinated future work on industrial colour‐difference evaluation

Recent results of research work on colour‐difference evaluation are reviewed in reports of two CIE Technical Committees; however, a global solution of the problem is still lacking. Therefore, guidelines for planning new research work are included in those reports. Here, these guidelines are explained and extended to stimulate new studies in a coordinated way, which could improve modeling of colour‐difference evaluations for industrial applications.
