The plugs look fine at first glance but a higher resolution image may show something different. The cylinder the "black" plug came from is definitely too rich but it is not that bad. Hm, the other ones look like they may be running hot. Can you provide a picture with better focus and more detail?

I replaced all four coils, all four spark plugs (see pic), and got a new battery. The next day, I got a CEL for cylinder misfires on 1, 3, and 4. Any idea what else it could be?

Regarding the plugs - three are almost identical looking, and I don't remember where each was from. The black plug was from the driver's front cylinder (#1?).
