Blue Is the Only Color in the Rainbow by Deanna Hart
Jasmine loves the color blue. She only plays with blue toys, only wears blue clothes, and only eats blue food. When she gets a red monkey named Mango for her birthday, she refuses to play with him because he isn’t blue. But then Mango takes her to Prisma, a beautiful and colorful place, showing her just how wonderful all the colors of the rainbow can be.
Using the colors of the rainbow, especially with the color blue, teaches children about the value of diversity and accepting the world around them.
