The pattern that comes to my mind with those two colors, is variations of those two colors and make a log cabin with the one diagonal being the one color and the other half the other color, and then lay it in a design - someone posted one very recently on this site and it was gorgeous. It was of purples and light colors and it zigzagged back and forth in a beautiful design. Wish I'd bookmarked it - and my memory for who the quilter was does not come to mind.
