Hi,
I just love red anything. I work with recycled wool garments. In my Wool Dye book, the author explains that you can use Tide powder no bleach to wash out extra color in the wool. I like to use primitive colors and black wool has LOTS of extra pigment in it. So I wash it twice in Tide and then I dry it in a HOT dryer. Then, I simmer it on the stove in vinegar water to make sure it sets up. The water is generally clear after the two washings in Tide, so I'm sure that is all you have to do. Tide will pull color out if you accidentally do what you just did - which is why I never use it to do my laundry.
Hope this helps! -Tori-
