I researched this from reviews on makeupalley and reccomendations from specktra.
If you have pink tones NW i would go with strada because it is a pinkish brown and it had awesome reviews on MUA.
If you are warm toned NC go with coppertone/blunt people liked coppertone/blunt a lot more than harmony. [me as well] They are pretty dark blushes so a little on your brush goes a long way.
