gray plugs?? detonation?

i just checked my spark plugs and they all had grayish tips. does this mean that my engine is detonating? i haven't even boosted the turbo yet nor have i gone over 4k rpm. please tell me it's ok. thanks.

Check again and make sure that they're not actually a light brown color. Under the wrong light, they can look grey.
