I have what I assume is a PH shift but I could be wrong. I have a dark green carpet (nylon) with a tan design and a tan carpet (nylon) with a green diamond pattern. They could be coordinated carpets from the same manufacturer. Anyway I used rust remover (for rust spots) on both of these carpets and the green dye turned a bright blue. The color didn't change when the rust remover was applied but during drying. I know what I might start with but wanted to get others opinions. So help me out guys. Thanks.
