Flatten each dinner roll into an egg shape and place on a sprayed baking sheet. (The shape you originally create will fill out and distort while rising so make sure you emphasize the defining characteristics.)
Cover with sprayed plastic wrap and let rise until almost double in size.
Mix egg yolks with food coloring to get desired colors.
Remove wrap from rolls and paint with colored egg yolk as desired.
Bake at 350°F 15-20 minutes.
