Round shape for wheel of the year, cycle of seasons
Skins are different colors, but the inside is the same chocolate, because we are all related.
Associations with the colors: Red = south, Green = West, Dark Brown = North, Yellow = East, Orange = For the solar God, Light Brown = The Earth Mother (Copper Woman), Blue = Sky Father. (Blue throws off the balance. Maybe the added color blue is a conspiracy to rid M&M's of the controversial association with Wicca.)
Rotate the M&M: M = 13th letter of the alphabet, and traditionally 13 witches in a coven; 3 = triple goddess, phases of the moon; W = witchcraft, wiccan; E = Enlightenment, Enchantment of chocolate.
"Melt in your mouth, not in your hand" = God/dess's love must be experienced directly to appreciate.
Sweetness = to remind us of how sweet the love of the God and Goddess is!
