Researchers at D.D. Williamson conducted an informal taste test with students between the ages of 16 and 18 to determine whether the color of a beverage impacts its flavor perception. The subjects were given three carbonated soft drinks — one with a clear color, another with a brown color, and the last with a pink color — and asked to describe how each tasted. All three beverages had a lemon-lime flavor; however, a majority of the students responded that the beverages had different flavors. For instance, more than one-third of taste-testers described the pink soft drink as “fruity,” “berry,” or “sweet.”
