I swore off sorting laundry by color for a full 8 weeks and nothing bad happened except one pink sock
Used to split every load by whites, darks, and towels, but last March I said forget it and threw everything in cold water at 6th and Main Laundry, and the only casualty was one white sock that turned a little gray, so now I want someone to tell me why I wasted a whole Saturday morning on this for a decade.
