That matches the gummy experiment. Buy a bag of cheap gummy candies, with multiple colors of candy. Separate the colors. Taste each color in turn, and write a description of the flavor that matches that color. Now put on a blindfold, and have a confederate hand you randomly selected candies. For each sample, describe the flavor. For certain brands (or lack thereof), it is readily apparent that all colors are actually the same flavor, and any distinctions that may occur in the initial descriptions are all illusionary. Some brands actually do have distinct flavors. At some point, someone figured out "hey, we could save money by not using 5 different flavoring blends, and most people wouldn't even notice." And it's not the smelling or tasting part that changes. It happens when you try to describe it. That's why "blue raspberry" is so wrong on your shaved ice. Raspberry is not a "blue" flavor. It's "red". But on the shelf, the red spectrum is already cluttered with cherry, strawberry, and watermelon. Apple has to be green, and raspberry has to be blue, so the ice jerk doesn't have to read labels. And you then have to close your eyes to make it taste more correct--or at least as correct as the artificial flavorings can get.
