Preheat oven to 350°F (175°C).

Divide cookie dough into 3 equal parts and color each part with 5-7 drops of red, orange, and yellow food coloring.

Wrap each dough color in plastic wrap and refrigerate for 30 minutes.

Divide each colored dough into 1 cm balls. Roll the balls together to form one large ball.

Flatten the dough with a rolling pin and use cookie cutters to cut out shapes.

Bake for 5-8 minutes or until edges are lightly golden.
