Spark plug picks

This is my odd cylinders. From right to left. What does the greenish color mean? My even cylinders are like that too. Thanks in advance.

It's probably the cheesy chrome plating that E3 uses on their ground straps burning off.

His: '00 WJ 4.7 Limited- Some stuff

Hers: '03 WJ 4.7 Laredo- Some more stuff

I don't use any additives. And they have been in there a long time. Almost 2 years.

They're heavily oxidized. It's not too uncommon.
Next time though I'd switch out those E3s for copper plugs.

Probably 15. I put them in about two years ago.
