Semantic Colouration Space Investigation: Controlled Colouration in the Bark-Sone Domain

This paper investigates the multidimensionality of colouration perception. Here spectral variation, a dominating physical acoustic property for colouration, and its relationship to the colouration perception was studied. A method for converting colouration specified in the bark-sone domain back to the operational magnitude-frequency domain was next formulated. A colouration space was then derived from common factor analysis using both verbal attributes from listening tests and colouration generation control parameters. The results show that one of the two dimensions of the colouration space was intuitively explainable and matches well with the control parameter.
