CONTRAST:

- Photography. the relative difference between light and dark areas of a print or negative.
 (excerpt from www.dictionary.com)
You could have a low volume of quilts, meaning that you only have a few of them, as VOLUME speaks to an amount or quantity of something.  But if you are talking about the lack of differences in the prints in a quilt, that quilt would lack CONTRAST, "the relative difference between light and dark areas of a print". Volume already has a plethora of definitions, I don't think it needs other.
