Color is a core element of visual art and also the starting point for students to perceive and express beauty. Based on the core literacy concept of the curriculum, this research builds a high school art classroom model centered on color around the teaching logic of "perception - understanding - expression - creation". Teaching design emphasizes the integration of experience and exploration, relying on the appreciation of masterpieces, color experiments and students' creations to form a symbiotic process of emotion and aesthetic thinking. Research shows that this teaching approach can effectively enhance students' visual perception and artistic expression, guide them to construct aesthetic consciousness through real experience, and establish artistic confidence in self-expression in creative practice.
