I use the "natural" ecru, cream or muslin color W&N on nearly all my quilts. I did buy a package of warm and white that I found on sale. I did not find a big difference since the color did not show through at all. . I had one quilt that the longarmer suggested that I use black and the "feel" of the finished quilt was quite different. They sent the scraps of the back batting home with the quilt and I would not use it again. I don't know the brand. Just like anything else, it is good to get your fingers on the batting to make sure you like the "feel" before committing to use any batting, color or not.
