This article takes Atlas silk as its research object, employing methods of literature review and semiotic analysis to study its historical evolution, visual characteristics, and cultural symbolism. It focuses on analyzing the formation reasons and socio-cultural significance of the main colors of Atlas silk, exploring the cultural logic of its color system and its translation into modern design. Atlas silk uses black, red, and yellow as its core colors to construct a unique color coding system. Through innovative digital design, its colors have been reconstructed and extended in cultural and creative products, clothing, and other fields. Through the "color translation" within the contemporary design context, it provides new ideas for shaping regional visual images and revitalizing intangible cultural heritage.
