Louie Duck

Louie is the youngest with the green color palette. He is somewhat absent-minded, and the most childlike of the group. However, he sometimes notices things the others miss. While Louie wore his now-trademark green shirt in the earliest of cartoons, he sometimes sported a yellow shirt as well.

In 2017's DuckTales, Louie is portrayed as laid-back and content, with somewhat of a cynical sense of humor.
