So, one of the most controversial aspects of the Rings of Power series is the presence of elves of varying complexion. This greatly irritates fans of Jackson's trilogy. But let's consider whether these elves of varying complexion could have existed. And the answer lies in... Drumroll! Jackson's trilogy, and the answer is affirmative!
Let's first consider the Origin of Orcs.
According to Wikipalantir [1]
"According to the original version, which Christopher Tolkien took from the Annals of Aman in his Silmarillion , the origin of orcs was from elves. Melkor , even before the fall of Utumno , kidnapped lonely elves from Cuivienen and, with the help of torture and black magic, perverted their essence, giving them an ugly appearance and an evil disposition. Orcs served their master only out of fear, hating him deep down. Subsequently, Tolkien returned to this theory several times, noting the presence of elven blood in orcs as quite possible, but each time he abandoned it.
Christopher Tolkien chose the "orcs from elves" version as the most stable and less controversial, and his father repeatedly emphasized that, be that as it may, the legend of such an origin of orcs was indeed widespread among the elves. This version also became the most widespread in Tolkien adaptations (films, TV series, books, games).
Also, in [2] we can read:” The origins of orcs were explained in multiple inconsistent ways by Tolkien.[24] Early works depict them as creations of Morgoth, mimicking the forms of the Children of Ilúvatar.[24] Alternatively, as in The Silmarillion, they may have been East Elves, enslaved, tortured, and bred by Morgoth;[T 15] or, perhaps the Avari, the Elves who refused to go to Aman, turned "evil and savage in the wild”.
In the film, the concept of orcs' origin from elves was adhered to. As well as in other things in the Rings of Power - after all , Adar was once an elf, and became an uruk . And Uruk , in the Black Speech, means orc. Why can't we assume that, say, Legolas could become a light complexion orc, and Arondir - a dark complexion orc. Since orcs are descended from elves, let's look at the complexion of orcs depicted in the film. They literally come in a variety of complexion! From dark to light. Since orcs have different complexion (photos - the presence of several orcs of different complexion), then elves should also have different complexion.
