Sam drew out the elven-glass of Galadriel again. As if to do honour to his hardihood, and to grace with splendour his faithful brown hobbit-hand that had done such deeds, the phial blazed forth suddenly, so that all the shadowy court was lit with a dazzling radiance like lightning; but it remained steady and did not pass.

From the LOTR Prologue, Concerning Hobbits:
‘The Harfoots were browner of skin, smaller, and shorter, and they were beardless and bootless...
From reading many British childrens’ books while growing up (many written in the early to mid 1900s), tanned skin was usually called “brown”. It meant tanned white skin. Not the dark brown of of for instance African, Arab or some Asian skin.
Tolkien was using “brown” in that sense.
“Schwarzenegger” means “Black Plowman” according to Arnold’s own statement years ago on the Dick Cavett show. Cavett wondered how the Shriver’s reacted to a “Black Plowman” joining the family, which elicited a smile from him.
