Like I have said dozens of times. To understand the Moors, you have to understand Berbers. "Moor" to me is complex because during later periods Moors meant all "races". Here's a paining of "Moors" posted on the Moors Wikipedia page.
Yeah those are Moors INDEED, but are they Berbers? Thats the big question. Are they the original invaders of Iberia? Again me don't think so. We know that non-black Muslims soon outnumbered black Muslims in Iberia and again that Moors soon meant Muslims in general. So showing a white painting of the Moors is not really a good case of showing the true origins of the "Moors". This is why "Moors" is complex.
Anyways these are the people who would have been the "Moors" in early periods. BEFORE the Almoravids.

Again they were literally what you called the "Moors". They were the most widespread Berber group and the most organized. They characterized by their extremely dark skinned.
I can post more evidence if need be. Trust me.
