明解色彩判別能検査と青の異常

Anomalous Color Sensation for Blue as Detected by Concise Color Discrimination Test

I．はじめに

　色覚異常問題を勉強していると，現在一番不合理で問題になり，改めようとすれば改められる点は，入学，就職の時の色覚制限であることを痛感する。

　現在の色覚制限は，色覚異常と色彩判別能を不合理に混同している。色覚適性基準は色彩判別能検査をもとにした合理的なものでなければならない。

A total of 400 color-defective subjects were examined by means of concise color discrimi-nation test of the author at which the exami-nee is asked to place various color paper strips upon their counterparts upon the test chart. Evaluation of the nature and degree of color anomaly is made according to the trend and frequency of errors made in this pairing pro-cedure. It was found that errors were often made in the blue range by subjects with red-green color amomaly and that the severity of color sense anomaly could not be grouped in a few, clearly defined categories but arranged along a sloped line without interruption.
