What is zapote color?

As an AI language model, I don't have access to visual information, but based on my research, zapote is a fruit that varies in color depending on the species and ripeness. Some varieties of zapote, such as the black zapote, have a green skin that turns brown or black when ripe. Other types, like the mamey sapote, have a rough brown skin that can range from light to dark brown. Inside, zapote fruit usually has a soft, creamy texture and a sweet, tropical flavor.
