Divide pudding equally into 5 bowls. Die each bowl respectively; yellow, green, blue, pink, and purple. (In case you forgot, blue+red=purple.) Each bowl will take about a drop of dye, but color concentration is up to you on this one. For stronger colors, add more dye until the colors are how you would like.
Drizzle each color of pudding into the pie crust, alternating colors as you go along.
When finished, take a toothpick and swirl around colors.
Add desired amount of glitter toppings. No amount is too much.
Serve or allow to set in refrigerator until ready for consumption.
