My colors are pretty much like the original DJ because I'm using civil war reproductions. My backgrounds are all white on muslin, and I got enough of one white on muslin for sashing.
I agree with esqmommy, I'm not sure this is the quilt to use black & white. I've seen a version where it is blue & white and it just didn't seem the same. The different colors make it look more complex, IMHO.
Another consideration is the size of the print, since these are such little blocks even a medium size print can get lost. Some of the pieces are only a 1/4 to 1/2 inch in size, so little of fabric shows.
Hope this helped
