NCS-Based Extraction and Innovative Application of Lingnan Traditional Color Palettes in Packaging Design

This study examines the traditional Lingnan color spectrum, establishing a quantitative analysis framework using the natural color system (NCS). Field surveys and equipment measurements extracted typical colors from architecture, embroidery, and ceramics, combining colorimeter data with multispectral photography to create a dynamic database integrating chromatic values, material properties, and cultural semantics. Findings show Lingnan colors are shaped by both nature and culture, with monsoon-driven vegetation and Danxia mineral hues forming base colors, while clan rituals and folk beliefs reinforce cultural identity (e.g., “bright red signifies fortune”). Applying “parametric continuity–scene regeneration,” desaturating colors by 20–30% and increasing brightness by 10–15 points improved youth acceptance (81%) and boosted sales conversion (herbal tea packaging +37%). The NCS framework enables cultural heritage integration into modern design, with future research exploring AI and smart materials for interactive applications.
