For touch-ups of small holes or marks (less than an inch), you can use an angled foam brush to lightly dab paint on the spot.

Always take note of the paint finish (flat, eggshell, semi-gloss, gloss, etc.). The slightest difference in sheens can make your touch-up stand out. Gloss finishes are especially hard to touch up.

Reducing paint by 10 to 15 percent with a paint reducer can often help the touch-up paint blend in. Use a paint reducer recommended by the paint manufacturer.
