Well you would have to understand that Mexico is a mix, but not a perfect mix. Southern Mexican states have more Indigenous people, and mestizos there have more indigenous characteristics, but if you go to Northern states it won't be difficult to find blond people, that's because there were less native Americans in the north than in the south. Then you have to understand that the poorest states of Mexico are in the south, therefore a lot of people from the South emigrates to the US, and that's where Americans get the stereotypical look for a Mexican. As an anecdote, I live in a Mexican Northern state, in my last year of college I got the opportunity to study as an exchange student in Charleston S.C., I went there with other 3 students, the three of them were what Americans would call "White", some people were confused, how a Mexican could be white? They had a clear picture of how a Mexican should look like, and usually that picture comes from Mexicans with a little more indigenous blood in their veins, as myself, I have black hair and my skin is clear brown even though two of my grandparents had blue eyes. So yeah, it all depends on where in Mexico you go, there are white Mexicans, native american Mexicans, even black and Asian Mexicans in the whole territory but we're part of a not so perfect mix, there are zones where one genetic pool is stronger than the other.
