In many folklores and literatures, green has traditionally been used to symbolize nature and its embodied attributes, namely those of life, fertility, and rebirth. Green was symbolic of resurrection and immortality in Ancient Egypt; the god Osiris was depicted as green-skinned. It is often used to describe foliage and the sea, and has become a symbol of environmentalism. Someone who works well with plants is said to have a green thumb or green fingers, and the word greenhorn refers to an inexperienced person. A company is said to be greenwashing if they advertise positive environmental practices to cover up environmental destruction. Green is used to describe anyone young, inexperienced, or gullible (probably by analogy to unripe, i.e. unready or immature, fruit). Green was the traditional color worn by hunters in the 19th century particularly the shade called hunter green. In the 20th century most hunters began wearing the color olive drab, a shade of green, instead of hunter green.
