Should be a little bit brown in the middle. Some carbon round the outside is OK - running rich is better than running lean.

The colour will only be a good indication of fuelling if the heat range is correct for the spec/use.
Looks very dirty to me, and rich, but as you say could just be was taken from a cold engine bad piccie etc.
If the plugs are particularly cold running more soot will deposit, esp under gentle use.
Mine are a milky coffee colour all the time, then edge towards white slightly after a long gentle run.
