some arguably are a little castizo at least (1/4 not 1/2), and also Spain has rarely been very ethno-centric, for better or worse, although whiter/more iberian+mediterranean genes have always been liked more. Even now many family members of most of Spain, not even very old ones, are shocked to hear if any youngsters date arabs, and beyond andalucia dating arabs is like being a korean and dating an african, it's really that rare and sort of quietly socially pressured against
Some from Andalucia do look like Sicilians / southern Italians, but in general southern Italians can look a little darker/more mixed. I think this might in part be due to Italy having an island even further south, and it might not even genetically be that they are more mixed, rather just darker.
One thing I would say is important here though is the facial structure. I have come to notice that even the darkest person on average looks european in their nose, eyebrows, mouth, jawline, even compared to very light Moroccans for example.
Probably the one drop rule applies here, even in terms of Arabs and not just subsaharan Africans. Very little admixture of the caliphate that invaded Spain can easily overwhelm many prominently presented phenotypes such as skin colour being light brown as opposed to pinkish, eyes being brown-green and hazel to dark brown, and hair being even jet black and curly not straight. Also chest hair and sometimes beard growth. These are very obvious when looked at on the outside, but genetically there is often very very little admixture in Spaniards despite this, hence their facial structure, generally middle European build (not Nordic tall but clearly taller than south/southeast of Europe, and athletic/slim built), Spain's IQ etc.
Spain has its great past scientists/inventors and artists/writers, (Don Quijote is supposedly the oldest novel in Europe, and known worldwide), Spaniards easily assimilate into other cultures, even other Western ones, and generally there are little to no despicably negative stereotypes of having Spanish neighbours in foreign lands. They're just Spanish, and that's cool, and maybe they have sweet Spanish food. Do remember that America's 'melting pot' has always worked best when whites/Europeans mixed, and even great differences such as the Irish compared to the Italian compared to the British Americans and all the tensions it brought is nothing considering their progress working together and compared to Arabs or Asians or Indians or Africans self-segregating and very rarely working together in a tight enough unison to achieve wonders.
So yea, a little admixture, often silenced by Nordic Circlejerkers (of Spanish and even non-Spanish origin) (no disrespect to Nords), but also often greatly exaggerated by liberals wanting against purism and nationalism, or globalists pushing for 'we are all the same.'
Spain is just too big and tall (north to south) that the 'average' Spaniard can have quite the range of phenotypes, it may touch France, Portugal, and Morocco, which many other EU countries touch others too, but France and the French who might immigrate can be more Nordic and/or Germanic (even considering south France looks more Mediterranean), and the south walls off the Arab world, plus the history of the Arab invasion.
You know, during past empires, Greece used to be paid, for free, for being a wall to Turkey from the rest of Europe. Spain never really got any benefits from anyone (not that it ever asked or needed any) for being the other border from the Arabic world.
One of my biggest sources of endless rage is that, aside from obviously 'diversity' being nearly all African mixing, and some Arabic sometimes (take a look at Paris 2016 holy fucking shit), the biggest irony is that Europe, even if you just take West Europe, is literally the most diverse place in the world by a fucking longshot. One could not speak for a greater length of time for any other continent than for Europe. Nobody else has every hair colour, every eye colour, and most builds (bearmode to athletic, flat tits to huge knockers etc).
In my opinion, is Spain white? Most clearly are, some are but not fully, very far and few are only partly.
Is Spain European? For now, yes, it is still of good enough genetic stock that it is European. Whether it can come back or it is doomed to fail eventually ever-so-slowly, only time will tell.
And no, lel, Spain isn't Europe's Mexico, everyone actually wants to go on holiday there.
Also that party I mentioned earlier did a new blog on the latest globalist shit, general world news but also a lot on specifically Spain
