Duncan just wants to color but when he opens his crayon box he finds only letters. Letters from his crayons all saying the same thing - his crayons have had enough! Blue needs a break from coloring the sky and the ocean. Orange and Yellow are no longer speaking for each believes they are the true color of the sum. Black wants to be used more. Duncan must find a way to make all of his crayons happy so he can color his new picture.
After reading, students can pick a color and come up with some more grievances they might have and write letters to Duncan telling him about. When students share their letters the whole class can come up with a way to solve each crayons problem so that Duncan can color again.
