Touch it up with whatever the original finish was...so in your case base/clear. If it's an actual door ding that requires bodywork then you will need to blend your color into the surrounding area and clear the entire panel for it to look right and hold up. If we're talking rock chips then you can dab some color into it and then clear on top. Add enough clear for it to sit just above the rest of your paint surface. Once it's fully cured wet sand down to 2500 without going too crazy on it and polish with a machine.
