If everything on your desk is black, why not go with a black and blue setup for the board? So get a set like
https://www.originativeco.com/products/classic-black, and then use the blue accent keys from the whitefox kit if you are getting it.
Though if you are buying the barebones kit (so without keycaps), then you will have to get blue accent keys elsewhere, but I think that would look pretty good on a whitefox. I have WoB cherry keys on mine with some grey arrow keys and it looks nice on the board, so I would imagine the classic black keys would as well.
