Only 8% of Mexicans are direct Spanish descendents. 30% are pure native americans, and 60% mulatto. The vast majority of the latter population is primarily indigenous, which means ethnic physical features would put them in the nebulous realm of PoC. This is true for most of Central America also, but further south it's more complicated, though in many ways similar, except for Argentina and Chile.
To really go to the root of all this I recommend Race and Human Evolution, by paleontologist Milford Wolpoff. Interesting to note most Mexicans and other immigrants from the south that I know, and having worked for the LA school district that is a very large number, do not consider themselves to be 'white' but hispanic. I knew the head of the language department at Garfield High in LA, and he wrote a paper on what a confusing misnomer 'hispanic' was. It literally means out of Spain, which of course as the numbers indicate is hardly the case.
Ok. How does that apply to Ricardo Montalban, the son of Spanish parents who emigrated to Mexico? And what colour is 'hispanic', that he's called a Person of Colour? (I do know what it means, and I've pointed out how ridiculous it is here before now.)
Yay.
