Cross‐modal matching between colour and music guided by objective physical attributes

Abstract Audiovisual synaesthesia is a common phenomenon in life and has many applications in entertainment, industry, construction, commerce, medical care, education and other fields. This study starts with the objective physical attributes of colour and music and examines the matching mechanism between them at the physical layer. Specifically, first, a colour and music database is constructed, from which the objective physical attributes of colour and music are extracted. Second, a subjective evaluation experiment of audiovisual cross‐modal matching is systematically implemented to score the relationship between colour and music. Third, based on the matching data, the correlation between the objective physical attributes of colour and music is analysed. In conclusion, this study utilises a multiple linear regression algorithm to develop audiovisual cross‐model matching models that link the objective physical attributes of colour and music, thereby empirically confirming the relationship between them.
