Difference scaling experiment was conducted to investigate the mental color representation of congenital color-deficient observers and observers with normal color vision. Two decks of cards, high and medium chroma, each containing 10 Munsell chips, were prepared. A total of 45 pairs of hues were prepared for each of the decks. Ten protans, 10 deutans, and 10 people with normal color vision participated as observers, with each asked to rate the perceptual distance between two colors on a given color card. The results were analyzed using the multidimensional scaling method. All observers with normal color vision showed a circular shape close to the Munsell hue circle, while the majority of color-deficient observers showed a concave shape bending at Y and PB. To indicate the degree of distortion from a circle, the distortion index was proposed to quantitatively evaluate intergroup and individual differences. To investigate the underlying mechanism of intergroup differences as well as individual differences in color representations of observers with normal color vision and color-deficient observers, we proposed a model that considers various levels of human color vision mechanism from the cone pigment absorption, the luminance and opponent-color coding level, and nonlinear transformation to difference-scaling judgment. The circular shape for observers with normal color vision and some color-deficient observers, as well as concave shapes for most color-deficient observers were estimated. The correlation coefficient between the estimation and experiment-based difference ranged from r = 0.64 to r = 0.94 with the grand average of r = 0.82, with p-values less than 0.001 for all observers, suggesting that the concept of proposed model is appropriate.

正常和先天性红绿色缺陷的颜色表示：基于色觉模型的个体结果估计

进行差异缩放实验以研究先天性色觉缺陷观察者和具有正常色觉的观察者的心理颜色表征。准备了两副牌，高色度和中色度，每副包含 10 个孟塞尔芯片。为每个甲板准备了总共 45 对色调。10 名 protans、10 个 deutans 和 10 名具有正常色觉的人作为观察者参与其中，每个人都被要求对给定色卡上两种颜色之间的感知距离进行评分。使用多维缩放方法分析结果。所有色觉正常的观察者都呈现出接近孟塞尔色环的圆形，而大多数色觉缺陷的观察者在 Y 和 PB 处呈现凹形弯曲。为了表示圆的变形程度，扭曲指数被提出来定量评估群体间和个体差异。为了研究具有正常色觉的观察者和色觉缺陷的观察者的组间差异以及颜色表征的个体差异的潜在机制，我们提出了一个模型，该模型从视锥色素吸收、亮度和对手颜色编码水平，以及对差异尺度判断的非线性变换。估计具有正常色觉的观察者和一些色觉缺陷的观察者的圆形，以及大多数色觉缺陷的观察者的凹形。估计和基于实验的差异之间的相关系数范围为为了研究具有正常色觉的观察者和色觉缺陷的观察者的组间差异以及颜色表征的个体差异的潜在机制，我们提出了一个模型，该模型从视锥色素吸收、亮度和对手颜色编码水平，以及对差异尺度判断的非线性变换。估计具有正常色觉的观察者和一些色觉缺陷的观察者的圆形，以及大多数色觉缺陷的观察者的凹形。估计和基于实验的差异之间的相关系数范围为为了研究具有正常色觉的观察者和色觉缺陷的观察者的组间差异以及颜色表征的个体差异的潜在机制，我们提出了一个模型，该模型从视锥色素吸收、亮度和对手颜色编码水平，以及对差异尺度判断的非线性变换。估计具有正常色觉的观察者和一些色觉缺陷的观察者的圆形，以及大多数色觉缺陷的观察者的凹形。估计和基于实验的差异之间的相关系数范围为我们提出了一个模型，该模型考虑了从视锥色素吸收、亮度和对手颜色编码水平、非线性变换到差异尺度判断的不同层次的人类色觉机制。估计具有正常色觉的观察者和一些色觉缺陷的观察者的圆形，以及大多数色觉缺陷的观察者的凹形。估计和基于实验的差异之间的相关系数范围为我们提出了一个模型，该模型考虑了从视锥色素吸收、亮度和对手颜色编码水平、非线性变换到差异尺度判断的不同层次的人类色觉机制。估计具有正常色觉的观察者和一些色觉缺陷的观察者的圆形，以及大多数色觉缺陷的观察者的凹形。估计和基于实验的差异之间的相关系数范围为r = 0.64 到r = 0.94，总平均值为r = 0.82，所有观察者的p值均小于 0.001，表明所提出模型的概念是合适的。
