It depends on the Latin American country. They all are the conglomeration of many distinct cultures across Africa, Europe, the Americas and sometimes Asia.
For example, some countries have stronger African influences than the others. The Spanish Caribbean (Cuba, PR, and DR) have strong African influences when it comes to music, food, their dialects, and even the appearance of many of the people on the islands. They also have pretty strong European influences as well. I would say the native (Taino) influence is not as strong as African and European in these places even though others suggest otherwise.
I think South and Central America has more native and indigenous influences with some European and occasionally African. For example, Mexica strongly identifies with indigenous (Aztec/Maya heritage). They even have lots of indigenous languages (like Nahautl)
Also, in South America there is a widely spoken indigenous language called Quechua. The people look more native and some are mestizo. Whereas only a few are mulatto or black (exception being Panama and Colombia).
On the other token, Argentina is mostly white and has strong cultural influences from Europe including Italy, Spain, Germany, UK, etc.
It really depends on the country you are referring to.
