Are you sure it's the insulation changing color and not the copper on the inside? The former is harmless, the latter is not.

Yeah, it's the copper inside that has changed color due to perfectly normal copper oxidation. The insulation is clear; you can see the copper inside it. Over time, the older wire may or may not develop shorts. Until it does, I wouldn't worry about it. If it develops a short, replace it. It's not a big deal. Copper exposed to air or water will oxidize and turn greenish. It's just chemistry.
