One is a book written and illustrated by Kathryn Oteshi. The theme in this story is about standing up for your self and others. This story is about colors who are being bullied by red and are feeling uncomfortable in their color. One day a number one comes and makes them laugh and have fun red gets mad that there not scared of him anymore. They all stand up to red to get him to stop bullying, in the end, they are friends and are happy. My thoughts on this  book are that its a very nice book and a great lesson for younger students.
