This article models multicolor perceptual features to investigate human perceptual responses to multiple colors based on a subjective evaluation experiment. First, an image set containing 164 multicolor samples was constructed, and multicolor objective features containing two categories with 60 dimensions were designed and quantified. Based on this, the 164 samples were evaluated by 30 subjects based on nine perceptual descriptive variables, including “swell‐shrink,” “light‐dark,” and “far‐near.” Then, a mathematical model of multicolor perceptual features (nine descriptive variables) was established by support vector regression. Finally, this article conducted model evaluation and factor analysis, and the results showed that the model could predict multicolor perceptual features well. It was also observed that, unlike single‐color perception, space perception was produced when applying multiple colors.

人类对多种颜色的感知响应：多色感知特征建模的研究

本文对多色感知功能进行建模，以基于主观评估实验来研究人类对多种颜色的感知响应。首先，构建了一个包含164个多色样本的图像集，并设计并量化了包含两个类别和60个维的多色目标特征。在此基础上，由30位受试者根据9个感知描述性变量（包括“胀缩”，“明暗”和“极近”）对164个样本进行了评估。然后，通过支持向量回归建立了多色感知特征（九个描述变量）的数学模型。最后，本文进行了模型评估和因素分析，结果表明该模型能够很好地预测多色感知特征。还观察到，与单色感知不同，
