There is a fair bit of ambiguity right there, but consider the fact that you don't even know if it's been pinned to the recommended pin numbers (maybe pinned to compensate for key wear) and that you don't know if it's got .005 pins or .003 pins using the colors you could probably narrow the pins value down to about 25 possibilities...
If you know the brand of the lock, you already know the possible bottom pin heights.
