Human emotions induced by colours are various but the emotions are expressed through words and languages. In order to analyse the emotions expressed through words and languages, visual assessment tests against colour emotions expressed by twelve kinds of word pairs were carried out in Japan, Thailand, Hong Kong and UK. The numerical expression of each colour emotion is being tried as a formula with an ellipsoid-shape resembling that of a colour difference formula. In this paper, the numerical expression of 'Soft-Hard' colour emotion was mainly discussed. The application of colour emotions via the empirical colour emotion formulae derived from kansei database (database of sensory assessments) was also briefly reported.
