I have never separated my clothes and have never experienced colours running.

just use warm instead of hot water
though i suspect it has to do with water quality
our water is high PH and probably alot of minerals and shit from old pipes, i never feel clean after showering
maybe you need softer water for the colors to leech from clothing
>>22880757this. Whatever colors there are,I mix it all
>>22880899>>22880757i am the same, and to add to this, i live by myself and i just don't go through enough clothes to do separate washes anyway.
