what color is wasabi

True wasabi, which is a semiaquatic herb native to Japan, is naturally green. However, most of the wasabi we eat is not true wasabi, but rather a mixture of horseradish, mustard, starch, and green food coloring or spinach powder. This imitation wasabi is often labeled as wasabi, but it does not include any part of the wasabi plant. Therefore, the color of the wasabi we typically eat is green, but it is not due to the natural color of the true wasabi plant.
