An Adjusted Error Score Calculation for the Farnsworth-Munsell 100 Hue Test

The Farnsworth-Munsell 100 Hue Test, a test that measures an individual’s hue discrimination ability, operates with the fundamental assumption that it is administered using a fixed, standard illuminant. This assumption is violated when the testing illuminant is changed—as is common when testing color discrimination ability of an illuminant—which likely causes a reordering of the caps in the test. To ensure that a participant is not falsely penalized for correctly responding to a hue transposition caused by the new testing light source, an adjusted error score is proposed that reconciles light source–induced hue transpositions and participant performance on the test.

范思峰-孟塞尔100色相测试（Farnsworth-Munsell 100 Hue Test）是一种用于评估个体色相辨别能力的测试工具，其实施的核心前提为：必须采用固定的标准光源开展测试。当测试光源发生变更时，该前提便不再成立——而在测试某一光源的色彩辨别能力时，光源变更的情况十分普遍，这大概率会导致测试所用色帽的排序出现错位。为避免参与者因新测试光源诱导产生的色相移位而被错误扣分，研究人员提出了一种修正错误得分方案，该方案可协调光源诱导的色相移位与参与者的实际测试表现，从而消除光源因素对测试结果的干扰。
