color in
Crayon an outline
To color in is to fill an outlined area with color, typically using crayons, markers, or pencils: The children colored in their drawings.
The phrase emphasizes completing or filling what was previously empty or outlined, distinguishing it from coloring generally.
Adults use it for coloring books marketed as relaxation: I like to color in while listening to podcasts.
