I use Shout color catchers with every laundry load. I don't sort my colors any more. The box of them are inexpensive at Walmart and I use whatever detergent is on sale, none of my clothes get dirt dirty so any detergent will clean fine. I test dark colored fabrics to see if I need to wash them first. No use wasting time and money if they don't bleed. I always wash my quilts after they are made and I use a couple of color catchers.
