The drink changes color and flavors as it's swirled, according to Starbucks. At first the Unicorn Frappuccino looks like it's purple with swirls of blue. But once it's stirred, "the color transforms from purple to pink, and the flavor evolves from sweet and fruity to tangy and tart. The more swirling, the more the beverage magically transforms!" Here at TODAY Food, we found that the color change was very subtle and not as drastic as we expected.
