I would lay several colors next to it and watch the changes in the way they look. White has a tendancy to wash out the colors it surrounds. Black or really dark colors will overwhelm and be center stage. Personally, I would go with a mid-range tone and use a color I love. A blue may be too much or just right for you. Any of the colors in your gorgeous fabrics or even a repeat of one of the fabrics would be great. Now that I have completely confused you, I will go fix supper.
