Everyone likes blue food better, or, at least, it's not really any worse than the non-blue food. The company that made blue food coloring had made it almost completely flavorless, and once all the food distributors got used to including it, the price had skyrocketed. Rival blue food coloring companies had come up, even some existing food additive businesses had shifted their focus almost entirely to producing blue food coloring. "All our food contains some amount of blue food coloring, but you can ask the chef in the back to remove it if you'd like". I can't even shower now, as blue food coloring comes out of the taps.
