My two cents here --- my family has one or two of the original feedsack quilts running around --- the white fabric was from flour sacks in our case --- sometimes it came in printed fabric most of the time in white. Over the years it has held up well color wise. Yellowing tends to happen if around smoke or not cleaned as often as it should've been. These are utilitarian quilts made to be used. So, I would opt for a natural cream tone on the lightest side if not using the white. If going for a color, go with the palest tint available. We are so fortunate to have fabric choices available and the $$$ to spend on our hobbies.
