Research on the Application of Shangri-La Regional Color Extraction in the Design of Cultural and Creative Products

The regional colors of Shangri-La in China have high representativeness and research value. This study aims to explore the regional color extraction method using the K-means++  clustering algorithm for the extraction of Shangri-La regional colors and apply the extracted colors to the design practice of Shangri-La cultural and creative products. The study includes: selecting representative pictures as data samples; using the K-means++ clustering algorithm to carry out scientific color extraction, outputting a network model of Shangri-La's regional colors, a standard master color card, and a color matching design guideline, etc., and completing the design practice; and collecting users' evaluations through questionnaire surveys and quantifying the results by using a five-level Likert scale. The results show that the color extracted based on the K-means++ algorithm is very characteristic, and its application to cultural and creative product design can reflect the cultural characteristics of Shangri-La and have a good color-matching effect.
