Consumer Reports may be correct about catchers not working in mixed clothes loads. I wouldn't know since I separate clothes into darks, lights, and wash anything new like a red sweatshirt separately. OTOH, if C.R. is saying catchers don't work at all, they are incorrect.
I wash like-colours together. I throw in a Shout catcher and, if it's drenched in colour, I send the load through another rinse leaving in the first catcher and adding a second one.
You can really tell the difference: the first catcher will pick up even more dye and the second catcher will be lighter. Repeat until the newest catcher is white or pale.
The Shout Colour Catchers work! I rarely need to do a third rinse.
FYI, I wash the like-colour fabrics just the way I expect the quilt to end up being washed: warm wash, cold rinse with Tide Free. I put the catcher in at the beginning of the wash cycle.
Shout is the only brand I've tried. I stock up when they are on sale.
