A microscope shows us that black pepper isn't really black. The berries are picked from the vine when they're green and then allowed to sit in the sun for a while. A black fungus called Glomerella Cingulata grows on the skins. That's the only part that's black - the fungus. Green Pepper is made by skipping the fungus-growing part.
White pepper starts off as green pepper, but the green skin is rubbed off.
Your jeans get their start in cotton fields. Cotton comes from plants that grow in the southern parts of the United States. On each plant, creamy blossoms emerge about eight weeks after farmers plant the seeds. The blossom eventually falls off, leaving a tiny ovary on the cotton plant that ripens and enlarges into a pod called a cotton boll, which contains a fluffy white material. People harvest the cotton fiber to a gin where machines separate the fiber from the seeds.
