coloring inside the lines

Staying within boundaries

Coloring inside the lines means following rules and conventions, staying within established boundaries.

The phrase comes from children's coloring books, where keeping crayon marks within printed outlines shows care and control.

Adults use it figuratively, often with slight disdain for excessive conformity: He's the type who always colors inside the lines.

Someone who doesn't color inside the lines is creative, unconventional, or reckless—depending on the speaker's view.
