Characters

Blue
It's the main character
He is a very rational and calm color. He is organized, and loves to follow the rules although sometimes he is extremely methodical and not very flexible with his opinions.

He is the most intelligent color and gets along very well with the other colors, which always ask for help. He is not very expressive and nothing makes him lose his calm (or at least almost nothing)

In his free time he is dedicated to reading all kinds of books, organizing his clothes meticulously or teaching Red to read and write.
