Paint is the cheapest way to change a room, but it’s also the hardest to keep up with. The bright blue that a ten-year-old loves can feel babyish by the time he’s thirteen.
The 12 colors below are grown-up enough to last into the late teens but still feel right for a younger boy. Each one is a real, widely available color you can match at any paint store. Always test a sample on the wall first, since colors change with your room’s light.

Tips for Choosing a Color That Lasts
Pick a color with gray or muted undertones rather than a bright primary. Muted shades feel more grown-up and are easier to decorate around as his tastes change.
Let him have a say. Narrow it down to three or four colors you’re happy with, then let him make the final pick. Use eggshell or satin finish so the walls are easy to wipe clean.
