Abstract
We designed a new protocol requiring French adult participants to group a large number of
Munsell colour chips into three or four groups. On one, relativist, view, participants would be
expected to rely on their colour lexicon in such a task. In this [ramework, the resulting groups
should be more similar to French colour categories than to other languages categories. On
another, universalist, view, participants would be expected to rely on universal features of
perception. In this second framework, the resulting groups should match colour categories of
three and four basic terms languages. In this work, we first collected data to build an accurate
map of French colour terms categories (Experiment 1). We went on testing how native French
speakers spontaneously sorted a set of randomly presented coloured chips and, in line with the
relativist prediction, we found that the resulting colour groups were more similar to French
colour categories than to three and four basic terms languages (Experiment 2). However, the
same results were obtained in a verbal interference condition (Experiment 3), suggesting that
participants rely on language specific and nevertheless perceptual, colour categories. Collectively,
these results suggest that the universalist/relativist dichotomy is a too narrow one.
