To me, common tern and roseate tern looks very similar. How can I identify them?

There were a few days this past summer when I repeatedly took the ferry between Cheung Chau and Central. Common Terns were present much of the time. Mind you, they were of the eastern race longipennis:

On those Common Terns, even from a distance, I could detect a clear contrast between the grey wings and the white rump and tail. You will not see such a contrast on a Roseate Tern because the wings of a Roseate are of a much lighter shade of grey.
