Our sense of smell changes the colors we see, show scientists

A study in Frontiers in Psychology found that unconscious 'crossmodal' associations with our sense of smell can distort perception of colors. Participants adjusted sliders to change the color of a square, but their choices were influenced by the odor they smelled, such as perceiving coffee as a reddish-brown color instead of neutral grey.
