Colorless Green (2013)

The main character is involved in a karate class. Hand-to-hand combat in-class is show in a couple of scenes, including unnecessary roughness.

There is practically no violence or blood until the end when the climax hits. Even then, while realistic it is mild compared to other movies. Blood is shown dripping on an injured hand as well as some brief fight scenes, but nothing excessive or unusual.

Some drinking among teenagers is implied. No drunkenness or explicit use of alcoholic beverages is depicted.
