My own people's Houses would likely not be as recognizable to you as your Jinn would be to me. There are physical differences -- all save the Yendi and Jhereg have distinctive features -- but they are more in the matter of the shape of certain features of the face. Many accent this by choosing to wear their heraldic colors, though there are exceptions.
