As long as your engine is running good and the spark plug reading is saying things are okay, I wouldn't worry too much about it.
My plugs looks OK at very light brown in color. I think it only happens when I use the headlight as it runs via the white wire,...could it be the cause robbing power therefore the plugs not efficiently burning the fuel?
