Nice I hope you spent a good time in Mexico.
We have an interesting mix of races here in Guatemala. I see that it in a positive way.
Guatemala shares a border with Mexico and are similar in many ways, for the good and bad. To the people of united states, british or almost any european country are called white guy, gringo, or canche = "blonde" by the majority of guatemalans(generalization is a stereotype for convenience) but yet again it is related to the situation. I had been called here by my own countrymen as canche, chino = chinese, ladino = mix of anything with mayan descent and called other ways no big deal etc, as you may see there is no pattern related on appearance to follow just to call the people that differsfrom you in other way. And we have a lot of ethnicities here. (and you can imagine the mix I am and how I look xD)
Yet there is the context in everything, it will depend the way is called and the demeanor. There are people that are black, mayan, asian descendants in Guatemala and the ones that are my friends I call them negro, negri, negrito, and viceversa they said chino, canchito, chinito, canche, chini etc (but you can also see people that just met by some minutes interact by the same way, it depends the intention is said)
As I can say "I love you" with sarcasm and "I love you" with real meaning. I see it that way.
