Quilt With Fugitive Color

I've had this old quilt for years and years. When it was first made, all the red baskets were RED. But one of the reds was fugitive, and 'beiged" out. I'm intrigued with how those parts placed themselves with built in randomness.

When It's Not Washed Out

I've done a test to tell if my fabric is sufficiently colorfast. That is: will it bleed color when wetted or washed. I've put the printed fabric on top, wool batting in middle, then white solid fabric on bottom. Sew a few rows, wet with spray bottle or soak, and let dry. Bleed through is no good.
