It depends on the paint; does it have any metal flake in it? How old is the paint and what condition is it in?
If it is a single stage or base-clear coat paint, try blending it with body lines and or gaps, that way the eyes has a break between the repairs. If you have to do it on a panel with no gaps or body lines it is more difficult. You will need to feather out the paint, (spray color that is reduced more) to blend into the existing paint.
Check you tube; there are some good videos out there on the process.
