The sculptors of ancient Numidians *my picture* clearly show that they were had mediterraneans features, not negroid ones
Your avatar is a Graeco-Roman stylization anyway and cant be used as a proof how ancient Berbers looked like. For that i would suggest that you just check the coins of ancient Numidia.
This coin from Massinissa seems to not be a stylization, atleast anthropologicaly. Just check his hooked nose and the beard: (Except of some late-era coins Numidians are always depicted with voluminous beards, and that not only on coins but on every other depictions like tombstones):

As north Africa has a mediterannean climate you can be to 100% sure that ancient Berbers north of the Atlas were no black Africans, but just looked similiar to the Carthagians, maybe just a bit more darkskinned in some cases.
