If a non-creature permanent becomes a creature temporarily and receives a counter, that counter will remain even after this permanent stops being a creature. For example, if a Celestial Colonnade is ‘animated’ by its activated ability and receives either +1/+1 or -1/-1 counters, those counters will remain on the Colonnade even after it stops being a creature. These counters will have no real effect while the Colonnade is not a creature. However, if the Colonnade were to become a creature again the counters on it will still apply and affect its power and toughness.
