Colored sticky corn is generally white, yellow, red, purple and black, among which white, yellow and purple corn are the basic colors. If the purple gene of the purple-white hybrid "beats" the white gene, it will naturally become purple, and vice versa, so if the two are tied, we will see white and purple corn. Purple can become red and black corn, or as we often say, "red is purple and black is purple".
Among these colorful corn, the most common Yellow Waxy Corn is the most nutritious because it is rich in carotene.
