In traditional Japanese medicine (Kampo medicine), tongue color is important in discerning a patient's constitution and medical conditions. However, tongue color diagnosis is susceptible to the subjective factors of the observer. To investigate factors involved in tongue color diagnosis, both color discrimination and tongue color diagnosis were researched in 68 Kampo medical practitioners. Color discrimination was studied by the Farnsworth-Munsell 100 Hue test, and tongue color diagnosis was studied by 84 tongue images. We found that overall color discrimination worsened with aging. However, the color discrimination related to tongue color regions was maintained in subjects with 10 or more years of Kampo experience. On the other hand, tongue color diagnosis significantly differed between subjects with <10 years of experience and ≥10 years of experience. Practitioners with ≥10 years of experience could maintain a consistent diagnosis of tongue color regardless of their age.
在传统的日本医学（汉方医学）中，舌色在辨别患者的体质和病情方面很重要。然而，舌色诊断容易受到观察者主观因素的影响。为了研究舌色诊断涉及的因素，我们对 68 名汉方医学从业者进行了色觉和舌色诊断研究。色觉通过 Farnsworth-Munsell 100 Hue 测试进行研究，舌色诊断通过 84 张舌象图片进行研究。我们发现，整体色觉随年龄增长而恶化。然而，在具有 10 年以上汉方经验的受试者中，与舌色区域相关的色觉保持不变。另一方面，舌色诊断在经验不足 10 年和≥10 年的受试者之间存在显著差异。具有≥10 年经验的从业者可以根据自己的年龄保持一致的舌色诊断。
