Against the backdrop of the accelerated branding process of geographically indicated agricultural products, issues such as homogenization of packaging color design and superficial expression of regional culture have become increasingly prominent. This article aims to explore innovative applications of color in the packaging design of geographically indicated agricultural products. The study first employs the theoretical analysis framework of 'cultural origins—design translation— market recognition' to examine the semantic composition and functional dimensions of packaging color. It then reviews common issues in the current application of color in agricultural product packaging. The core part proposes a systematic innovation path: extracting regional color genes through tracing origins, achieving creative transformation of cultural semantics into design language through translation, and constructing a brand color framework through systematization—forming a culturally rooted color system. The article further applies modern design language for translation and implementation, ultimately achieving a unity of regional cultural identity, brand recognition, and product functionality. This research aims to provide a theoretical basis and methodological reference for enhancing the cultural value of geographically indicated agricultural products and shaping differentiated brand images.
