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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
