In this paper, through the analysis of the poster color of the classic, jazz and rock music festivals in different ages, the synesthesia characteristics of music and color are explored, and the poster color is extracted by software. It is found that different music festivals have different poster color styles. For example, rock music mostly uses bold colors and bright contrast colors, while classical music mostly uses overt natural color features. Like music, the rhythm of rock gives people a sense of excitement, while the rhythm of classical music is more fluent and balanced. Through case analysis, it is concluded that color is the external spiritual embodiment of music.
