The "Compulsory Education Art Curriculum Standards (2022 Edition)" clearly define "aesthetic perception, artistic expression, creative practice, and cultural understanding" as the core competencies of art curriculum, emphasizing that art teaching in compulsory education should follow the laws of students' physical and mental development, stimulate students' learning interest through fun and life oriented curriculum design, and help students solidify their artistic foundation. The research aims to explore scientific and effective art teaching strategies based on the actual laws of color cognition among lower primary school students, in order to solve the problems of insufficient pertinence and weak e ffectiveness in current teaching. In the research process, we wi ll first analyze the core significance of carrying out art teaching in lower grades based on color cognition laws, and then explore strategies for carrying out art teaching in lower grades of primary schools based on color cognition laws in combination with teaching practice, in order to provide operational teaching references for art teachers in lower grades of primary schools.
