Keeping your quilt out of direct sunlight is also a good idea. On a related topic, i used fabric 'confetti' to mulch my perennials last year. THe bed is in direct sunlight. Most of the scraps from recycled men's shirts retained their color, as for the actual quilting fabric scraps, it really varied. Cost didn't seem to matter, some inexpensive ones are as bright as when I put them out there, and some of the costlier ones faded. Different colors from the same fabric line faded at different rates so it might be the dye use. Actually, i would say that the reds fared worst.
