some closer to Native American (Taino).

But most are mixed. Most of the Puerto Ricans I know don't racially identify as white or black, but as Latino, Spanish (meaning Latino) or specifically Puerto Rican. The vast majority of these folks were brown to light brown with mixed white/black/Native features.

This generally applies to most Caribbean Latinos I've known, which is why the change to the Census to mark "Hispanic/Latino" as only an ethnicity and not a race resulted in many Latin folks writing in "Puerto Rican", "Cuban", etc. (see http://www.pewresearch.org/fact-tank/2014/04/04/mexican-hispanic-and-latin-american-top-list-of-race-write-ins-on-the-2010-census/)
