I still have red and red & white patterned towels in the kitchen, but everywhere else we have become a white towel household.

White.
For all our blood, sweat, and tears, but mostly grease, beer, and whatever.
Hot water wash. Bleach.
Natural devolution from proper bath towels and bar towels, to cleaning cloths, to rags, to bike rags.
I guess we could use them for kindling if we had a wood stove, but we don't.

It has simplified my life more than I would ever have imagined.
