We tested out rainbow eye-shadow palettes from Wet n Wild, NYX, Sugarpill, Jeffree Star Cosmetics, and Viseart to find the best one. We tested the palettes on their shade ranges, their color payoff, and their blendability. In the end, the Jeffree Star Cosmetics Jawbreaker palette came out on top because of its easy-to-blend formula, wide range of colors and finishes, and vibrant color payoff.
