“Down the face of a precipice, sheer and almost smooth it seemed in the pale moonlight, a small black shape was moving with its thin limbs splayed out. […] The black crawling shape was now three-quarters of the way down, and perhaps fifty feet or less above the cliff's foot.[…] They peered down at the dark pool. A little black head appeared at the far end of the basin, just out of the deep shadow of the rocks.”
No visual version of Tolkien’s works could ever be made now which depicts Gollum accurately.
I grant you that it’s not clear-cut, but nowhere in the book (that I can find) is Gollum described as being pale, or even lightly colored (except his eyes). Instead, Gollum is frequently, as I showed, described as being “black” in color. He is also being misidentified as an Orc, which are similarily described.
