People from Morocco have very little Arab admixture & genetically they’re closer to West Africans than any other group. Their haplogroup is below:
The only Arab influence there is the fact that they’re mostly Muslims (that came with the Ottoman Empire) & some of them speak Arabic. However, the overwhelming majority of them speak Berber languages. And Berbers are all over North & West Africa & they come in different shades - from very light, to very dark skin shades.
A lot of the admixture in Morocco has a lot to do with European migration due to its proximity to Iberian peninsula - not cos they’re Arabs.
Most of the people from Morocco I see online are also saying they’re Africans not Arabs. Ditto all the Moroccans I know.
So, what does The Coli think?
