Preheat griddle over medium heat. Spray with nonstick spray.
In a large bowl, combine bisquick, milk, eggs, sugar and vanilla.
Once combined separate batter equally into six bowls.
Pick the color you'd like for each bowl. Put several drops of coloring into the bowls until desired color is reached. For orange, combine yellow and red. For purple, combine blue and red.
To cook the pancakes, use a small measuring cup and drop six small pancakes on greased griddle or pan heated to medium.
When pancakes start to bubble, flip.
Serve with butter and syrup.
