I am chuckling over this because my SIL is exactly the same. Everything she owns is a shade of brown. The only other color she considers as an accent color is the green that is the mint layer of an andes mint candy. Sadly, as much as I love her, there was no way I could make little girls quilts in brown. So the first got pinks with that light green and hints of a milk chocolate brown (less than 10% of quilt). She actually hung the baby quilt in the baby room! Stunned I was. The second girl came around and I did purple/green and no brown, and she shocked me again and said she loved it for kendall. And then she turned around and begged me for a table topper, all in browns, go figure. Maybe the mommy will come to accept color for the little one. Good luck.
