For over 100 years, popular and scientific communities have suggested that colours have psychological and affective implications (Kaya & Epps, 2004; Major, 1895; Wexner, 1954). Yet, most claims remain unsubstantiated, including the assumption that the actual perception of colour is a key ingredient to any such supposed implication. Since 2015, we have been systematically studying and publishing results on colour-emotion associations for colour terms and colour patches using the same overall methodology, testing different populations. We could already show that emotion associations with colour terms are highly consistent across different cultures, but that consistencies are even higher when cultures share borders and languages (Jonauskaite, Abdel-Khalek, et al., 2019; Jonauskaite, Abu-Akel, et al., 2020; Jonauskaite, Wicker, et al., 2019). For a Swiss sample, we also found high consistencies for emotion associations with colour terms and colour patches (Jonauskaite, Parraga, et al., 2020). These results indicate that such associations are majorly driven by conceptual mechanism. To elaborate on this latter point, we manipulated perceptual colour experience by testing individuals with and without congenital red-green colour-blindness. The first group experiences colour perception deficiencies, but both groups’ conceptual knowledge is comparable. We asked congenital red-green colour-blind (n = 64) and non-colour-blind (n = 66) men to associate 12 colours with 20 emotion concepts, and rate the emotion intensities. About half of each group provided associations with colour terms, the remainder with colour patches. We found that colour-blind and non-colour-blind men associated similar emotions with colours, irrespective of whether colours were conveyed via terms (r = .82) or patches (r = .80). No differences occurred when we categorised emotions according to valence, arousal, and power. Of interest, the colour-emotion associations and the emotion intensities were not modulated by participants’ severity of colour-blindness (CBI). Hinting at some additional, although minor, role of actual colour perception, the consistencies in associations for words and patches were higher in non-colour-blind than colour-blind men. Together, these results suggest that colour-emotion associations in adults are driven more importantly by conceptual mechanisms than direct perceptual experience of colour. Therefore, intact colour vision is not essential for having shared colour-emotion associations. The current findings add to a growing body of literature that colour-emotion associations represent another psychological universal.
