I agree with everyone else above.

I don't know what "standard exception" you're referring to. As described, what you did is a clear call. As madlex said, in a low stakes game you might be able to get a floor to give you a warning and let you raise anyway, but the chances of that significantly dwindle once there is a call behind you.
I can only think of two exceptions to the oversized chips rule (and neither is so standard that you should rely on it), neither of which is what happened here:
1. You have enough in chips already out to cover a call (because at least one was oversize when originally bet), so adding even a single additional chip is not required to call, so it can be ruled a raise.
2. You take back the chips already bet (in this case your 7), and throw them out again with your oversize chip(s).
Neither of the above are actually written into the rule, they are just experienced interpretations, so you are highly encouraged to verbalize your action anyway to avoid having a ruling go against you, even in these cases.

Don't do this. Large denom chips must be clearly visible, and go on top or in front. You risk having them ruled out of play for a hand (or worse yet, out of play if you win, but in play if you lose) if the floor thinks you are trying to hide them. It's a bad habit to get into.
