Comment on Does it really matter if you use white or colour detergent for washing clothes in a washingmachine?
Thorry84@feddit.nl 7 months agoNew stuff should definitely be washed on it’s own a couple of times, before being mixed in. New stuff can easily give off enough color to make a white shirt pink for example when washed with a red thing.
Just because you’ve been lucky or maybe have a lot of same colors where it doesn’t matter doesn’t mean it’s a general rule to go by.

Doesn’t that only happen in nim-cold water washes?

No? Why would it only happen in non-cold water?
When the clothes are first colored they use too much dye, because using too little ruins a batch of clothes whilst using too much is only bad for the environment but good for making money. The surplus of due can’t adhere to the fabric, so the first couple of times you wear/use and or wash the clothes the extra dye comes off.
I had a dark green bed sheets give off blue dye onto my white matrass cover. I didn’t wash the together, but the extra dye still came off in use. Obviously water will help the dye become mobile a lot, but it isn’t necessary. I’m not sure if the temperature has any effect at all.

I’ve only heard of/experienced colour bleeding in warm/hot water washes. I (thankfully) haven’t experienced colour bleeding with cold water washes.
