The colour category PURPLE is strangely heterogeneous, potentially due to the use of different cognates. We asked French speakers from Algeria, France, and Switzerland (n = 274) to produce up to three free associations with violet (basic term), pourpre, and lilas (non-basic terms). We counted 2,075 associations. We developed a coding scheme that i) covers nine major themes, and ii) shows high inter-rater reliability. Overall, the themes colour terms and natural elements and objects were most prominent showing that participants provided closely related associations. Finally, violet triggered more diverse semantic associations than pourpre or lilas. This was true for all countries. It seems that the basic term PURPLE carries more diverse associations and connotations than the non-basic terms
