Groot coloring page is a good way to relax and work with different colors to create a recognizable image of a comics book character. Now the whole world knows this guy as one of the Guardians of the Galaxy. Probably every movie theater on this planet has heard the phrase “I am a Groot”. However, this hero first appeared in the late 1960s on the pages of Marvel comics.
To color this guy in, use the typical tree colors. It is a light gray non-uniform color with lighter and darker areas. If you want to complicate this drawing, you can add a woody texture with a few broken lines that look like little slits.
