I bought these washcloths in teal, and I have used them for over two months with frequent washing. So far, the color is holding fairly well with minimal fading (washing on cold). However, that may not last very long because every time I use the washcloths there is a noticeable amount of dye present in the water when wringing them out. And yes, my first time washing with these was with vinegar to colorfast them. I still think they were a good purchase because the actual construction/sturdiness of them seems great - all of the stitching is intact. Keep in mind that these are significantly larger than the average washcloth though, so a person with very small hands (like a child) may not like using these.
