Blue-haired cartoon characters are animated characters with blue-tinted hair, a distinctive feature that sets them apart from other characters. A notable example is Smurfette, the sole female character in the popular animated series "The Smurfs".
These characters have gained significant relevance as they often represent individuality, rebellion, or supernatural abilities. Historically, blue has been associated with royalty, wisdom, and tranquility, making it an intriguing choice for cartoon characters.
