Blue is good, orange is bad. For some reason fuel is not being 100% burned in the cyl. When its burnning in the exhaust you get a blue flame. You'll need to research the problem, if evrything seems up to snuff I'd guess it to be the cam. When its orange you're melting the engine down.

a really good burn pattern on the plugs is a cocao brown not black (black is too rich)

drive hard or drive home
