How does food coloring change the taste of soda?

Food coloring itself does not alter the taste of soda, as it is primarily a visual additive made from dyes. However, the perception of flavor can be influenced by color; for instance, a brightly colored soda might be expected to taste sweeter or more fruity based on its appearance. This psychological effect can lead consumers to perceive a difference in taste, even though the actual flavor profile remains unchanged.
