I could make the same argument that we don't know if Tolkien intended to Dwarves to be Blue skinned because he wasn't specific, but we know from the overall narrative that this wouldn't be the case because if they were blue skinned, he would make the effort of going out of his way to describe them being blue. And narratively speaking, the Hobbits would make mention of skin tones that so wildly differ from their own.
That the Hobbits and the overall narrative doesn't differentiate Dwarves in a major way from the Hobbits who percieve them informs us that they would have been a skin tone that Hobbits would consider familiar and normal. So we can gather that the Dwarves wouldn't have had a skin tone that was that much different from that of a Hobbit's expectations, otherwise it would have been worth noting as much as is described of any general feature that seemed outstanding to a Hobbit (thick beards, big noses, dark hair, broader physiques, etc).
IMO, brown skin would be quite exotic to the Hobbits. So even though we don't know the true skin color of Dwarves, it's reasonable to assume it would be white (or variation of) because of the lack of description.
Even Harfoots in the appendices are mentioned to be 'browner of skin' than the Hobbits, and if such a detail is recorded then I can't imagine Dwarves being omitted from having a similar detailing if they were meant to have darker skin tones than that of Hobbits.
Since Dwarves were the creation of Aulë from the stone of the earth, we could assume they came in all sorts of colors that stone comes in. But if such a detail were so important, one could question why this was never elaborated on, especially in the eyes of the narrators.
