Taking the "simple color grading method" as the starting point, this study analyzes the role of this method in reducing learning barriers, establishing basic color cognition, optimizing teaching pace, and other aspects from the perspective of course requirements and classroom situations. At the same time, it points out that the color grading steps are overly simplified, individual differences among students are easily overlooked, and students have low interest in learning. On this basis, the study proposes strategies such as embedding color knowledge in clear steps, responding to different students through layered tasks and flexible requirements, and activating learning interest through situational activities and artwork display, so that the simple color matching method can be reasonably applied in primary school freehand flower and bird painting copying teaching.
