Preheat oven to 350 degrees.
Combine the dough ingredients in a stand mixer or use a hand mixer.
Divide the dough equally into four small bowls.
Add one ball of dough back to the mixer and add a drop of yellow food coloring. Mix until thoroughly incorporated. Return the dough to the bowl and repeat with the pink, then blue, then purple. No need to clean the bowl in between.
On a lightly floured surface, add the yellow dough and roll out. Make all of your cut outs and place on parchment lined cookie sheets, re-rolling as needed until all of the dough is used. Repeat with the three remaining colors.
Bake the cookies for 8-12 minutes or until lightly golden on the bottom. Do not let them get brown.
If oven-drying, reduce the heat as low as it will go and wait to put the cookies in until the heat subsides. Add the trays and allow to dry out, stirring every so often. This can take hours. If the oven is too hot, crack the door open or turn off the oven and turn on the in-oven light. Check frequently and toss so they dry, not brown.
Allow to cool completely and store in an airtight container.
