Recently I did run into a problem when cleaning clothes. Because of a new washing powder, my orange pant (that I use since more than a year now) did transfer a part of its tint to all other clothes. Those clothes being mostly white home clothes, white/gray underwear or yellow clothes for outside, it is not a problem (and it is even good for yellow ones btw). I did put one white skirt with all them, it did receive the same treatment and the color is really beautiful after that.
So, lesson learned: when anything change, even the least significant thing, I expect some clothes to rub off even the oldest ones.
Now, what's the problem? I wanted to add one (or two) pocket(s) to that skirt, by using pieces of the same clothing I did get when I shortened it. And as you can guess, the clothing is not anymore on the same color than the skirt, which is a bit problematic. I did try to make a pocket using the original textile with all corners sealed so that I can put it in the washing machine with the pant, hoping to get the same color. Bad luck, the orange tint is stronger in the pocket than in the skirt now

Here is a picture of the original skirt at left, the newly tinted in middle, and the pocket I was planning to add when it would have been of the right color (which I'm afraid will never happen)

Because I don't really want to try again and again and again to repeat the same operation (or with dyeing that I never tried before) until I get a nicely coloured pocket (if it even happens which is not sure) and also because I do not want my pant to become white

If you want to see what it will look like when it will be dry, I can take a picture of it with first pocket attached (with pins) and a piece of the white textile attached to act as if it is the second pocket.
With the actual residuals of the shortening, I have enough textile to do 7 other pockets (or maybe more by the cost of combining several small pieces). Btw, I will stop to use that new powder before to destroy all my clothes
