As far as I know, in the countries were Portugal set colonies up, mixed race kids were just Portuguese on account of having a Portuguese parent.
When the Revolution in Portugal happened in 1974, Fascism was brought down and most of the “colonized” countries became free (Brasil had been independent for over a century by then, so it was only nations in Africa) and any Portuguese national who wanted it was repatriated, quite independently of skin color, and many were mixed race hence why I think a large proportion of the mixed race offspring just got Portuguese nationality on account of having a Portuguese parent and was in a normal Portuguese family.
That said, I vaguelly remember that during the Fascist Dictatorship the authorities didn’t want mixed race people in Portugal, but after the Revolution nobody really cared.
I guess that during Fascism the Portuguese authorities were fine with people having mixed race kids as long as the whole thing happened in the “colonies” and stayed there.
Certainly the stories I’ve heard from that time don’t really include in the “colonies” the level of segregation I’ve heard about with for example the English in places like India, though in the “Homeland” it was different.
Not to say Portugal was or is some kind of Racism-free paradise. It’s probably culturally just a bit less elitist and relaxed about “enforcing rules” on people than many other European nations who had their own “colonization” projects.
And then of course there is the example of Brasil were there are all skin tones possible, so clearly for many generations a large percentage of people haven’t really cared about keeping races segregated since originally there were only white Portuguese, black African slaves and the natives, with the latter actually being the smaller fraction of the population. I see it as an indication that the dominant original culture (the Portuguese one of the XVI and XVII century), didn’t care much about stopping people from having sex across races.


Which generally comes with “I am more important than those forigners and hence should be treated better than them” which is just another form of “what’s in it for me”.
Certainly my experience from living in Brexit Britain is that the kind of people who couldn’t accept criticism of Britain were also the kind who though they were superior to foreigners because of being Britons and expected to be better treated than foreigners for it, and that wasn’t just in their own country but also for example when on vacations abroad.
