Red, red wine

How come it is next to impossible to get a red wine stain out of a white shirt, and yet as soon as inadvertently include a red shirt in with a white load in your washing machine you ended up with all those whites turning pink instead of bluey?

Can’t those dye chemists use whatever it is that makes red wine stain so well to fix the red pigment in that shirt so that it doesn’t come out in the wash?

Just a thought.
