Abstract
Experimental evidence demonstrates robust cross-modal matches between music and colors that are mediated by emotional associations. US and Mexican participants chose colors that were most/least consistent with 18 selections of classical orchestral music by Bach, Mozart, and Brahms. In both cultures, faster music in the major mode produced color choices that were more saturated, lighter, and yellower whereas slower, minor music produced the opposite pattern (choices that were desaturated, darker, and bluer). There were strong correlations (0.89 < r < 0.99) between the emotional associations of the music and those of the colors chosen to go with the music, supporting an emotional mediation hypothesis in both cultures. Additional experiments showed similarly robust cross-modal matches from emotionally expressive faces to colors and from music to emotionally expressive faces. These results provide further support that music-to-color associations are mediated by common emotional associations.

*The concept of emotion is notoriously difficult to define. Typical definitions identify emotions as “conscious feelings” that have both physiological and cognitive components, followed by a list of prototypical examples (e.g., fear, anger, joy, and sorrow) with no boundary conditions to clarify less obvious possibilities. Emotional associations are systematic connections between emotions and other mental states caused by experiences that are not intrinsically emotional, such as hearing music or seeing colors. As we use the term, emotional associations may include conscious experiences of feelings and/or cognitive content that accompanies such feelings.
