Don't you have any touch up paint?

I can't see a problem in your photo. Where is the scuff?

The two solutions are touch-up paint or ignoring it. If you don't have the original paint, trying to touch it up with a color matched paint would likely make something that is trivial more obvious.

Are you kidding?

I can't see the problem either, and I zoomed way in on the photo.

But I have to say, even for the most careful people, living in a house scars it up a bit. If you have kids or pets, all bets are off! I say, paint when it gets intolerable, or when you're ready to move. Until then, don't sweat the small stuff. But that's just me.

Will not be particularly obvious. Unless you have or can match the paint color exactly, ignore it until you're ready to repaint the entire room.
