Investigation of color vision and color appearance on dichromats. Expansion to new Kansei in color vision-

二色性受试者(颜色缺陷观察者)在没有对应于绿色和红色波长的颜色刺激(色片)的颜色命名任务中使用红色和绿色的颜色名称，对于颜色正常的观察者。此外，此条件下的色片与颜色名称之间的关系与正常观看条件下的结果具有良好的一致性。这些结果表明，对于二色性物质，红和绿的命名不一定需要与红和绿相对应的中波长和长波长。目前的结果与红-绿颜色对抗机制的反应很少或没有反应的假设是一致的。此外，实验结果还直接表明，二色性动物正在使用刺激强度作为颜色命名的线索。因此，本研究否定了另一种假设，即通过使用混合视锥和视杆，二色动物与正常颜色观察者具有几乎相同的色貌质量。

Dichromats(color deficient observers) used color names of Red and Green in the color naming task on chromatic stimuli(color chips) without wavelengths corresponding to Green and Red for color normal observers. Additionally, the relationship between color chips and color names in this condition was consistent well with the result under the normal viewing condition. These results indicate that, for dichromats, middle and long wavelengths corresponding to Red and Green are not necessarily needed for the naming of Red and Green. The present results are consistent to the hypothesis that the response of the red-green color opponent mechanism is little or none. Moreover, the results directly indicate that dichromats are using stimulus intensity as the cue of the color naming. Thus, this present study denies the other hypothesis that dichromats have almost the same qualia in color appearance with color normal observers by using hybrid-cones and rods.
