In the local expression of public art, the deconstruction and reconstruction of color symbols is an important pathway to activate the vitality of regional culture. This aims to break the long-established "essentialized" labels of regional color symbols by stripping away singular associations, reorganizing historical fragments, and excavating marginal symbols. By integrating contemporary contexts, technological means, and cross-disciplinary thinking, it endows traditional color symbols with new narrative logic and forms of expression, establishing a deep connection with contemporary society. The two aspects complement each other, allowing color symbols to escape the static predicament of being "regional specimens" while transforming them into dynamic carriers of historical memory that respond to the needs of the times. Ultimately, this promotes the local expression of public art from a simple replication of regional culture to a cultural dialogue that embodies both critical and creative dimensions, providing important support for constructing a vibrant urban color ecosystem.
