"Green-eyed" typically refers to a person who has green-colored eyes. Eye color is determined by genetics, and green is one of the rarer colors, resulting from a combination of low melanin levels and the scattering of light. People with green eyes may have varying shades, from bright emerald to deeper olive tones. In literature and culture, "green-eyed" can also symbolize jealousy or envy, often referred to as "the green-eyed monster." This phrase originates from William Shakespeare's play Othello, where jealousy is depicted as a destructive force. The dual meaning of "green-eyed" highlights both a physical trait and an emotional state.
