@raoul well, it’s bleached back with washing soda first; before the coffee bath. You CAN still get a nice color by skipping the bleach step, but I like to just bleach it just a very little, basically until I see the blue just START to fade, before a quick rinse and then into the coffee for about 20 min or so and then a final wash.
