In this study, our aim is to clarify the color combination rules of the human‐preferred Papilionidae butterflies as aesthetic objects. A set of 118 butterfly images, including color polyphenism from the 47 Papilionidae species that are generally preferred by humans, was selected. These images were classified using hierarchical cluster analysis based on similarities of lightness, chroma, and hue attributes in CIELAB space, determined using histogram intersection. Then, the color distributions and combinations in each cluster were analyzed using a Gaussian mixture model and the color combination types defined in the present study. Accordingly, we obtained the following main color combination rules of human‐preferred Papilionidae: (a) dominant low lightness and contrasting lightness components, (b) dominant low chroma and similar chroma components, and (c) dominant orange to yellow‐green hue and similar hue components. These rules partly agree with the robust harmony principles found in previous research. We infer that the cognitive effects concerning the processing fluency through these color combination rules influence human aesthetic responses.

凤蝶科蝴蝶作为美学对象的计算配色分析

在这项研究中，我们的目的是阐明人类偏爱的Pa蝶科蝴蝶作为美学对象的颜色组合规则。选择了一组118张蝴蝶图像，包括来自47种常见于人类的蝶形科的颜色多态性。这些图像使用基于直方图相交确定的CIELAB空间中亮度，色度和色调属性的相似性，通过层次聚类分析进行分类。然后，使用高斯混合模型和本研究中定义的颜色组合类型分析每个群集中的颜色分布和组合。因此，我们获得了人类偏爱的蝶形科的以下主要配色规则：（a）主要的低亮度和对比亮度成分，（b）主要的低色度和类似色度成分，以及（c）主要的橙色到黄绿色色调和类似的色度成分。这些规则部分与先前研究中发现的鲁棒和声原理一致。我们推断，通过这些颜色组合规则对处理流畅性的认知影响会影响人类的审美反应。
