Colour is a fundamental aspect of visual communication, influencing perception, emotional response, and user engagement in various fields, including art, design, marketing, and media. However, most of the available literature emphasises the universal principles of colour theory; the cultural aspects of colour, especially those from non-Western traditions, have not been extensively addressed. Classic Chinese colour schemes, inherited from philosophical schools such as Yin-Yang and the Five Elements, form a distinct and symbolically rich visual language. They are not just aesthetic elements, but also bearers of historical, ethical, and cosmological significance that express the richness of Chinese cultural identity. This paper presents a conceptual model that connects traditional Chinese colour schemes with the visual attractiveness of audiences. It emphasizes the intervening role of emotional response and the hermeneutic power of cultural symbolism in organizing aesthetic perception. The model speculates a linear chain by which traditional colour combinations influence symbolic meaning, which influences emotional responses that organize the viewer's general visual experience. Cultural familiarity is suggested as a moderator that can enhance or weaken these relations depending on the viewer's background and cultural knowledge. As a theoretical contribution, this study aims to provide a foundation for subsequent empirical investigations. Some of the methods that have been proposed include eye-tracking to examine visual attention, surveys to compare emotional and symbolic responses, experimental comparisons between conventional and unconventional combinations of colour, and cross-cultural investigations with various participant groups. By filling the gap between conventional aesthetics and contemporary design concerns, this research makes a useful contribution to both visual communication studies and culturally responsive design practice.
