Color damage

[hogjowl]

I ran into a carpet today that had a moving box size purple area under where the bed had been. It’s a rental and is empty. Upon close inspection, I found varying tones of purple all over the house in a broadcast pattern. It’s a brown carpet originally. My theory, for all it’s worth, is someone either cleaned the carpet with something that damaged the dye, or a flea treatment was performed, right before someone moved in. I say that because the box size square, deep purple stain under the bed suggests someone put a square object onto the wet carpet under the bed while the carpet was still wet. However, there’s no purple stains from furniture placement, suggesting I might be wrong there.
What do you inbreds (and Jim) think could have caused this. I realized everyone else (except maybe Pemberton) is guessing but I’m curious.

Got any pics?

I've not seen pesticide cause that sort of color change, but I suppose it is possible

Does the purple glow under UV light?

Is the carpet light or dark brown?

If you are going back, I'd pH test the purple to see if it could be an indicator dye situation. The only time I've seen dark purple on brown was when the carpet reacted to a highly alkaline degreaser that was used as a prespray. That took some acidic treatments, but after a few miscues (too much acid turning the purple to pink, then back to green, then orange, then finally back to brown) we fixed it.

This one is pretty interesting.

My wife says I’m color blind but I swear the carpets looked brown on site

Gray is more likely to have an indicator dye change tan brown. I’m thinking that could be the case, but hard to tell without testing

I think my wife may be right. In fact, I bet she’d tell me to go sit down somewhere.
