An nofficial bout

[PoeticAtHeart]

To compress, i was originally going to write a silly little tangent, instead i got stuck on whether i should use unofficial or inofficial, this seems easy, just pick one or the other, same with grey and gray, colour and color, but apparently people use inofficial and unofficial in different situations, so what i really wanna ask:

In what way would one sound right and one sound wrong when in the same sentence?
