Have never used a color catcher...If I have a bright fabric, I try and pre-wash it...mostly I don't pre-wash, though. I just wash quilt on gentle cycle, then gently shake it out, and dry it on gentle for a few minutes. When damp dry, I drape it to finish drying, smoothing it out as needed...never had a problem yet...I have done hand quilts and machine quilts, both...
By the way, I do have a high efficiency front load washer...
