I have carpet discoloration, how do I fix it?

[Rooster OG]

So I am getting ready to sell my Ford Explorer and I have some discoloration on the rear passenger carpet. I'm not sure what caused it but it looks like some sort of chemical, maybe bleached. Is there some sort of carpet dye I guess? Do I buy a bottle of hair coloring and hope for the best?

I'm just curious if there are any products or methods I could try to get it looking better.

303 Spot Cleaner or Folex Carpot Spot Remover with some agitation might work

That's not a stain. They make carpet dye or since it's black sometimes you can get away with just spray painting it lightly.
