Monsters are Red, Monsters are Blue — Sarah Albee

When Elmo makes friends with a blue monster named Angela, the two of them learn a lot through visits to each other's homes. They learn that they and their families have stereotyped ideasâ€"and prejudicesâ€"about red and blue monsters. Everyone is surprised to learn that blue monsters eat the same foods as red monsters and that reds enjoy the same games and TV programs as blues. Angela discovers Elmo has really nice friends of every color. The message in this story is handled with subtlety and humor.
