In a large bowl, combine flour, Dixie Crystal's Fine Granulated Sugar, baking powder, baking soda, and salt. Then add in the buttermilk, milk, eggs, and melted butter. Mix for 30 seconds and all ingredients are blended.
Separate the batter into 3 bowls. Then, make orange, green, and purple batter. See notes below on how much food coloring to put into each bowl.
Spray cooking spray in a frying pan and heat over medium heat.
Using an ice cream scoop, pour the batter into the pan.
Cook for 2-3 minutes until you start to see bubbles forming in the batter. Then flip and cook an additional 1-2 minutes until brown and cooked through. Remove from griddle and repeat until all the batter is used.
