I believe that doing anything more than tilt effect IS in conflict with the current guidelines. But, the "current" guidelines are soon to be the "old" guidelines, so who knows.
I will suggest that I think that doing both is confusing and too much. Having something tilt makes sense -- that happens in the real world. Having something change color makes sense -- we see that with mouseover effects on web pages. Having something do both for what the user perceives as a single action results in a confusing clash of the real and online worlds. Why not also add sounds or haptic feedback?
And I think that the answer is that subtlety is best. We want the user to recognize that something happened, but maybe not even know why they recognize it.
