I need to patch some concrete outside and I want to be able to
match the color (basically 'dirty looking') and make it look old &
weathered.

Pressure washing the old concrete first may reduce the need and produce a better
match after the first time it is washed after installation. You don't want to
match the dirt on the old concrete.
