THIS report is a brief, greatly simplified expression of the working hypotheses being used by color vision investigators today; a note on the ICI Coordinate System and Standard Observer; a short report on some of the developments resulting from Inter-Society Color Council (ISCC) and other activities; a notation of some typical color vision tests in current use, and an empiric classification of the types of color vision we have found in our studies.
The first two sections are simplified abstracts arranged, we hope, in a form easy to remember. The third section is really a news note and the fourth section hardly more than a short list of typical examples of color vision tests. For the fifth section we claim neither originality nor completeness. It is a practical, easily remembered outline into which we have been able satisfactorily to fit all the types of color vision so far encountered
