本报告遵循SPIE-IS+T/Vol.7528 7528051-8、SPIE-IS+T/Vol.7866 78660J-1-8和SPIE-IS+T/Vol.8292 829206-1-8。颜色在各种情况下都被用来传达信息，而不仅仅是用于设计和服装。然而，具有不同颜色视觉类型的个体可能会以不同的方式感知仅由颜色给出的视觉信息。人类的色觉是不一致的，在大多数情况下，这种变异与L视锥和M视锥有遗传联系。因此，颜色外观对于所有颜色视觉类型都不是相同的。颜色通用设计是一种易于理解的系统，它的创建是为了将颜色编码的信息准确地传达给大多数人，并将颜色视觉类型考虑在内。在本研究中，我们研究了三色(C型)、普罗兰(P型)和道坦(D型)三种颜色视觉形式。我们在这里报告两个实验的结果。首先利用CIELAB均匀颜色空间上的色卡对混淆颜色进行验证。我们制作了一张实验色卡(色细胞总数为622个，色细胞之间的色差为2.5)用于实验，受试者具有P型或D型色觉。从这些数据中，我们能够确定围绕各个基点的“易混淆的极限”和“可能混淆的极限”。前者的方向与理论上的混乱轨迹相吻合，但范围并不延伸到整个a*范围。后者在理论混乱轨迹的上方和下方形成带状区域。这样，我们重新分析了皮特-贾德提出的理论混乱轨迹的一部分。第二个实验是对C型、P型和D型色觉受试者进行颜色分类实验。FHE 100色调测试的色帽被分为7类，每种色觉类型。比较了每种颜色视觉类型的共同和不同的色觉感受点，我们能够找到一组C-、P-和D-型的人都能识别的颜色类别。这一结果可以作为未来色彩通用设计的色彩方案的基础。
This report is af ollow-up to SPIE-IS+T / Vol. 7528 7528051-8, SPIE-IS+T / Vol. 7866 78660J-1-8 and SPIE-IS+T / Vol. 8292 829206-1-8. Colors are used to communicate information in various situations, not just for design and apparel. However, visual information given only by color may be perceived differently by individuals with different color vision types. Human color vision is non-uniform and the variation in most cases is genetically linked to L-cones and M-cones. Therefore, color appearance is not the same for all color vision types. Color Universal Design is an easy-to-understand system that was created to convey color-coded information accurately to most people, taking color vision types into consideration. In the present research, we studied trichromat (C-type), prolan (P-type), and deutan (D-type) forms of color vision. We here report the result of two experiments. The first was the validation of the confusion colors using the color chart on CIELAB uniform color space. We made an experimental color chart (total of color cells is 622, the color difference between color cells is 2.5) for fhis experiment, and subjects have P-type or D-type color vision. From the data we were able to determine "the limits with high probability of confusion" and "the limits with possible confusion" around various basing points. The direction of the former matched with the theoretical confusion locus, but the range did not extend across the entire a* range. The latter formed a belt-like zone above and below the theoretical confusion locus. This way we re-analyzed a part of the theoretical confusion locus suggested by Pitt-Judd. The second was an experiment in color classification of the subjects with C-type, P-type, or D-type color vision. The color caps of fhe 100 Hue Test were classified into seven categories for each color vision type. The common and different points of color sensation were compared for each color vision type, and we were able to find a group of color caps fhat people with C-, P-, and D-types could all recognize as distinguishable color categories. The result could be used as the basis of a color scheme for future Color Universal Design.
