Spanish History Iberians

Do Spanish / Iberian tended to be darker?
I've been thinking and looking back in history and it seems that the Spanish used be (darker), centuries ago – as they were called black white and classified then apparently darker as Greek and Rome and other tribes lighter invaded Visgoths, vandals, etc. It is possible for them have been darker, but mixed with the Celtic and Germanic, since they look much lighter, Portuguese have Celtic origins over the centuries. I just want your opinion on this and if I think this is true or false, I really not sure why I have now and would like to know if someone has a memory of history older than me. This has been on my mind for quite some time, so I asked to see their views on the things, guys. (:
No, but the Celtic / Celtic-Iberians were dark (brown) and light-skinned and most important is that our ancestors. We're not even a group homogeneous, so some Spanish people are very fair and pinkish skin tone and some are olive color. Varies. Also, the Moors invaded us Germans after of Sarmitians / / Swabians and although many of the Moors brought slaves were mostly Slavs Berbers. Some Berbers can be a bit darker than the typical 'celtic' Spanish toned – but many also Berbers and Visigoths had light hair looked like, so it depends – some of them might have tipped the population to be darker and lighter ones. Mac & Cheese are native Celts of Iberia or one of the native groups and said they were dark-haired. No red or blond. The blonde came from German, Berbers and Slavs.
