The basic color of coffee beans the color transformation of coffee in a lifetime

Coffee has undergone several color changes from seed to cup. The coffee tree has white flowers, and the coffee fruit is born dark green, which gradually changes to yellow in the process of ripening and finally becomes red. The raw coffee beans are wrapped in the coffee fruit, washed, dried and processed to become coffee seeds wrapped in yellow parchment, then shelled and polished into a charming jade green, and then roasted to have a unique color. So much so that the word "brown" was derived.
