Changed plugs 1 step colder. How do they look?
Went to a 1 step colder plug. The one that looks darker than the others, top right in photo was from my drivers side closest to the firewall. Do they look decent? Does the one look fouled? Maybe too rich of a mixture? What could cause this on just one plug? Thanks in advance for any insight/help.

Reading plugs that have been driven on is a PITA, especially with just a single picture...
They look like normal plugs to me that have been driven on and have had race fuel or octane boost run through them at times. The 3rd from the left on the bottom looks darker to me, but that could just be lighting. As long as there aren't noticeable ash deposits and the plugs aren't wet with fuel or oil they should be fine.
Definitely close the gap and make sure all of them are the same.
