In a small bowl, combine the Bisquick mix, milk, and eggs until blended. Separate mixture evenly into 6 small bowls (around 1/2 cup each). Dye each bowl one of the colors of the rainbow (red, orange, yellow, green, blue, purple). Cook pancakes by pouring 1/4 cup of batter onto a hot greased skillet or griddle. This will make two pancakes of each color.
