Dear Fabio Gasparini,

Generally speaking, color naming , color semantics, color  categorization , and  shape of color space across different languages has long been an area of great interest in bilingual/multilingual studies. Prototypicality norms ( Rosch's model) have also been a matter of importance trying to examine how bilinguals tend to categories the tokens belonging to a given language type. I hope the following links shed more light on what you are looking for.

Best of luck,

R. Biria

Dear all,

thank you for your help! I am dealing with the topic from a purely linguistic perspective and I actually needed some references on cognitive approaches since this is not my proper field. Seems like I have a lot to read now, thanks!

Best,

Fabio
