Which was NOT about skin color at all, but about species (elf, dwarf, human, etc.) as well as about culture. That's the prime distinguisher of collective identity in practically his entire work, and while skin color clearly isn't absent (you've proved that sufficiently) it also isn't a main focus, and occurs only very sporadically.
The more important question then becomes not "what did Tolkien intend/consider important", but what do WE consider important - because we're interpreting his work in any adaptation, and we have to analyze what we're given based on certain criteria. And there really is practically nothing to suggest that skin color as a distinguisher is more important to the narrative he built than factors like species or culture (or even language). Which means that when creating an adaptation, we have to decide where to observe the source material, and where to deviate.
There is no question about that deviation, let's be clear - ANY adaptation WILL deviate in SOME way. It's purely a matter of deciding where and by how much. And given that there seems to be an overwhelming presence of species, language, and culture defining the relationships between the various collectives in Tolkien's works and only a vanishingly small amount of mention of skin color (let alone making it a direct driver of narrative as species, language, culture are in his works), wouldn't you say it's not unreasonable to largely disregard this characteristic in casting - considering we're disregarding all sorts of other details mentioned in passing, too.
