colour inside the lines

Follow the edges

To colour inside the lines is to follow rules and conventions, staying within prescribed boundaries.

The phrase comes from children's colouring books, where neatness means not straying beyond printed outlines.

It often carries a mildly dismissive tone, suggesting safe, unimaginative compliance: He's the type who always colours inside the lines.

Also spelled color.
