Should I be concerned about the coloration of these spark plugs? (lemmy.zip)

Bought this car second hand, they apparently put iridium spark plugs in, but i want to know if I should be concerned with the buildup and rusty appearance it's developed. For all I know this spark plug could be from 10 years ago.

Do I need to replace the plugs, and is that actually rust? Does this mean I have an issue with my head gasket?

Edit: Thanks guys! I'll be ordering some new plugs soon.

Obviously some common sense is involved, life experience. Obviously I’m only swapping out parts that a lifetime of wrenching on my own vehicles has taught me to.

And yes. At somewhere between 80-120k you WILL need new ball joints, tie rod ends, sway bar links, etc. and an alignment to finish it off.

Do you maintain your vehicle? Or just run it to fail?
