Error scores on the Farnsworth-Munsell 100-hue test were partitioned into those representing red-green and those representing blue-yellow losses. Data from two groups of normal observers were used. One group showed results characteristic of published norms; one group showed superior performance. Both observers showed a correlation between red-green and blue-yellow scores indicative of a strong performance factor in this test. The difference between blue-yellow and red-green scores eliminates their correlated variance and allows evaluation of the axis. Both groups showed an increase in difference scores, with age indicating development of a blue-yellow axis. This increase was significant for the observers characteristic of the norms. We suggest cutoff scores to allow a decision as to whether a given patient shows a blue-yellow or red-green axis.
法恩斯沃思-芒塞尔100色调测试中的误差分数被分为代表红绿色觉缺失和代表蓝黄色觉缺失的两类。使用了两组正常观察者的数据。一组显示出已发表规范所特有的结果；另一组表现出更优的成绩。两组观察者的红绿色觉分数和蓝黄色觉分数之间均存在相关性，表明在该测试中有一个强大的表现因素。蓝黄色觉分数和红绿色觉分数之间的差异消除了它们的相关方差，并允许对轴进行评估。两组的差异分数均有所增加，年龄表明蓝黄色觉轴在发展。对于具有规范特征的观察者来说，这种增加是显著的。我们建议使用临界分数来判定某一特定患者是否表现出蓝黄色觉轴或红绿色觉轴。
