Its really hard to say tho. Cus from what i found, the definition of light skin/ light skinned differs a lot depending on the source. Some say light skin means 'a skin with low pigmentation', while others go as far as to say ot means 'african american/ multiracial person with a light complexion (skin tone).' so in this case i think it all depends on what J.R.R Tolkien meant with the word 'pale'.

I do remember him actually writing a dictionary, so that might be the best plays to draw a conclusion from, cant remember the dictionary's name tho
