I have a scrappy Jewel Box on a black background and a couple different bright on black quilts. I like that combination but I have also seen it on a light background as you are describing.

Here is Jewel Box on a light background: http://www.quilterscache.com/J/JewelBoxBlock_Page2.html

There are also links to "real" quilts on the same page. Dorothy's & Gwen's are more like what you described.
