What does your favourite colour say about your personality? Not much Qu'est-ce que votre couleur préférée dit sur votre personnalité? Pas grand-chose

The claim that favourite colours reveal individuals’ personalities is popular in the media yet lacks scientific support. We assessed this claim in two stages. First, we catalogued claims from six popular websites, and matched them to key Big Six/HEXACO trait terms, ultimately identifying 11 specific, systematic, testable predictions (e.g., higher Extraversion among those who prefer red, orange, yellow, pink, or turquoise). Next, we tested these predictions in terms of the Big Six personality trait scores and reports of favourite and least favourite colours from 323 French-speaking participants. For every prediction (e.g., red-extraversion), we compared trait scores between participants who chose or did not choose the predicted colour using Welch’s t-tests. We failed to confirm any of the 11 predictions. Further exploratory analyses (MANOVA) revealed no associations between colour preferences and personality trait. Favourite colours appear unrelated to personality, failing to support the practical utility of colour-based personality assessment. peerReviewed publishedVersion
