In basic art education, guiding students to use colors for effective expression has always been a key part of teaching. However, current students' works often encounter problems such as color disorder, lack of prominent subject, ambiguous emotional expression, or inconsistent style. To solve these problems, research focuses on four key aspects: color coordination processing, visual focus guidance, subject feature expression, and style matching positioning. Corresponding teaching content, objectives, and methods are analyzed. It is hoped that through such discussions, specific references can be provided for frontline art teachers in color teaching, helping them to carry out color matching practical teaching more systematically and effectively in the classroom, ultimately improving students' artistic expression ability and work quality.
