Iridescent Velvet Fabric

I am specifically looking for iridescent velvet of 2 DIFFERENT colors. NOT ones that have a silvery pile or a lighter color over the same! Namely I would like to find it in silk, but if the color combination works for me, any blend will do. The preferable color combination would be a blue/indigo/purple backing with a brown pile Can be smooth, crushed or embossed. Will also consider a reverse coloring as well as several others depending. Looking for approximately 10 yds depending upon price.
