The mathematical model for colour preference in Chinese painting within museum lighting environments

Abstract Colour in a Chinese painting not only conveys cultural, historical, and philosophical concepts but also carries specific symbolic meanings and emotions, possessing a high level of artistic value. However, the sensitivity of Chinese paintings to light results in exhibition environments being characterised by low illuminance and low colour temperature. Therefore, accurately assessing colour preferences in Chinese paintings under such conditions is an issue that needs to be addressed. This study conducted simulated experiments in real museum exhibition halls, with 36 participants providing subjective evaluations of Chinese paintings, to explore the effects of various lighting parameters on colour preferences. Through statistical analysis and multiple linear regression, the relationship between lighting parameters and colour preferences in a Chinese painting was determined, and an evaluation model was established. This research outcome provides important mathematical tools for selecting appropriate lighting and developing dedicated lighting for Chinese paintings, ensuring the artistic inheritance of Chinese painting colours.
