Traditional color teaching mainly relies on textbook illustrations and teacher demonstrations, making it difficult for students to intuitively feel the diversity of color usage under different cultural and historical backgrounds. In this context, the research aims to explore the scientific application framework of digital tools in high school color teaching, systematically proposing four strategies: building a hierarchical digital resource system, designing immersive human-computer interaction tasks, using intelligent diagnostic technology, and building a multi-directional evaluation platform. Theoretical analysis is combined with typical case verification, in order to provide operable solutions for teachers to optimize color teaching by applying digital technology.
