colors inside the lines

Stay within boundaries

Colors inside the lines describes someone who follows rules and conventions without deviation.

The phrase comes from childhood coloring books, where staying within the printed outlines is the mark of careful, obedient work.

It often carries a mildly dismissive tone, suggesting a lack of creativity or independent thinking: He's the type who colors inside the lines—don't expect any bold ideas from him.
