Step-by-step explanation:
People wear marks of color on the forehead in India for several reasons. Some have religious meaning, but not only, another marks serve a social purpose. Vermillion marks signify welcoming; a round mark or a round, button-like red ornament on the forehead of a woman, called bindi, may mean she is married; a single girl may also wear a non-red bindi.
