　先天性色覚異常者の色命名能力について，第2報^1）において，背景白での視標の直径を小さくした場合の誤答内容について検討した。今回は背景色を黒にして同様の実験を行い，白背景の場合と比較検討を行つた。

In the previous paper, colour naming tests using pigment colours on a white background were applied to congenital colour defectives. In this paper, the same tests on a black background were attempted to 15 deuteranopes, 10 protano-pes, 31 deuteranomalies and 6 protanomalies. Test targets made of coloured papers were 1.5 mm, 4.0 mm and 26.0 mm in diameters. Hues using this test were yellow, blue, red, green, orange, purple, brown and gray. Test distance was 75.0cm.

Results of these experiments were compared with those of the previous experiments.
