I remember my mother would add "bluing" powder to the final rinse. I guess I
was "destined" for color management 😊

Back in the day, I was a chemist for P&G. Almost all laundry detergents have a
“brightener” added, to counteract the faint off-white cast of laundry. As
described, they absorb UV, and emit blue, which counteracts the slight yellow
cast of the laundry. Before the advent of brighteners, housewives would add
“bluing" to the final rinse. Bluing was a shaker bottle of a suspension of blue
dye.
See https://en.wikipedia.org/wiki/Optical_brightener for more details.
