For some time, the only documentary standard on color‐difference measurements within the American Society for Testing and Materials (ASTM) has been D 2244, “Method for Calculation of Color Differences from Instrumentally Measured Color Coordinates.” It was developed by ASTM Committee D–1 on Paint and Related Coatings and Materials, and currently includes only the three color–difference equations of particular interest in the paint industry, namely CIELAB, Hunter Lab, and FMC‐2. ASTM Committee E‐12 on Appearance plans to prepare a comprehensive standard, probably a Guide to the Selection and Use of Color‐Difference Equations. It will contain not only the three equations mentioned above but also a number of others. The Guide will also include tutorial discussion on the selection of equations for various color‐difference evaluation purposes. This article documents the history of color‐difference standards within ASTM. It also invites readers to contribute suggestions for material to be included in the proposed Guide.
