It's a difficult thing to read plugs with the fuels today. With the ethanol and oxygenated fuels not to mention the additives in modern fuels, you will usually get a white tip on the insulator of a plug regardless of the mixture unless it is overly rich. Colors are usually from the additives in the fuel now since the tetraethyl lead has been removed.
You can read deep in the plug where the insulator contacts the barrel with a magnifier to get somewhat of a reading but don't go by tip color for mixture adjustments. Ground strap coloration is an indicator of heat range if the color changes at the curve in the strap, it is about right.
