Whisk together play dough ingredients and divide into separate microwave safe bowls for each color you're making.
Stir in food coloring, one color per bowl.
Microwave for 1 minute, stir; microwave for 30 more seconds, stir. If needed, continue microwaving in 15-20 second intervals until dough begins to form and pull away from sides of the container (or is no longer soupy).
Allow to dough to cool enough to handle and finish mixing by hand.
