COLOR DISCRIMINATION IN STATIC DISPLAYS

Abstract

A description is presented of an experimental test of the color discrimination ability of a group of untrained observers in a simulated display situation in which stationary targets on a constant background are viewed. Just-noticeable-differences (JNDs) in saturation at constant brightness were determined for 39 subjects for each of six hue series about the 3200K tungsten achromatic point. The results indicate that human chromaticity discrimination ability is only moderately degraded for widely separated 1/3-deg target spots in a dark field subtending 17 deg. Evidence of tritanopic effects was found with the 1/3-deg targets, but the effects were moderate and are approximately accounted for in a scaling procedure. These findings may be applicable not only to the monitoring of reentry vehicles, but to other similar display situations in which color is used as an additional dimension.
