We know that colors modify odor’s perception. It demonstrates that colors arrangement (chromatic cards) could evoke the appropriate odor, but we have not neural evidence of these chromatic cards olfactory suggestion capacity. Our goal is to compare the olfactory suggestion capacity of picture with that of chromatic arrangements using functional MRI paradigm. We show that chromatic card visualization could suggest an odor more efficiently than picture visualization. Our results support the involvement of multiple cognitive processes (olfactory, emotional, visuospatial, language, memory, taste) which interact to produce olfactory suggestion from colors visualization. Therefore, chromatic card application could be varied (health, marketing…).
