Abstract:

Subjects of varying type and degree of color deficiency were tested on a battery of color tests, including the American Optical Company Plates (both 1940 and 1965 editions), the Dvorine Plates, the Farnsworth-Munsell 100-hue, the Farnsworth Lantern, the Farnsworth Panel D-15, the SAM Color Threshold Tester, the Titmus Vision Tester Color Plate, and an anomaloscope. Correlations with a daytime and nighttime practical test of the ability of subjects to discriminate aviation signal red, white, and green were obtained.

The results indicate that color defective people can identify flashes from a signal light gun better at night than during the day. It was also found that the Farnsworth Lantern, the SAM Color Threshold Tester, the two sets of A O Plates, and the Dvorine Plates were among the best predictors of performance on the practical test; the Titmus Plate was the poorest predictor.
