Those who have mainly enjoyed taro mixed with other foods find that the flesh of the root is surprisingly mostly white. Interestingly, it's the small purple dots that give taro its signature flavor. On the other hand, taro powder often uses purple food coloring to get the desired effect. In reality, the taro root's color can vary and include purple, pink, and white. This color depends on the quality of the soil it is grown in and the region.
