Just changed my spark plugs today.  I'm looking at my old spark plugs, and they look kinda like the lean condition pictures, but I can't really tell.  Can anyone tell me if this looks normal or not?

And



Also http://www.centuryperformance.com/spark-plug-reading-spg-192.html

First pic says Brown to grayish tan. The Century page says gray-tan to white

I know you probably looked at these already, just threw them up in case others haven't seen them yet.
