The "Daily Revision of the G eneral High School Art Curriculum Standards (2017 Edition, Revised 2022)" deepens the cultivation of core disciplinary literacy. The traditional single-period color teaching model has revealed issues, including a lack of systematic structure and relatively superficial cultural connotations. This article focuses on optimizing color teaching under the unit-based teaching model and proposes four practical strategies: unifying teaching through themes, progressing literacy step by step, relying on diverse techniques, and completing the loop with in-depth exhibitions and evaluations. By reconstructing teaching units, designing progressive tasks, integrating diverse creative activities, and implementing formative assessments, students’ ability to integrate and apply color knowledge as well as their creative expression can be effectively enhanced, providing an actionable teaching plan for achieving high school aesthetic education goals.
