The color of the snake in the dream is not necessarily significant unless the dreamer has a particular attraction or aversion to the color purple. Snakes can have several different, even contradictory meanings. In Western Culture, snakes generally represent evil, betrayal or dishonesty, in which case the dream could represent the dreamer's anticipation of trouble, particularly betrayal. However, the snake can also symbolize healing and regeneration as seen in the medical symbol of a snake twined around a staff. Other details of the dream as well as the emotional tone of the dream should signal whether it has positive or negative meaning to the dreamer.
