Our school colours correspond to Harry Potter houses?

...Okay...Make it two... (If Gryffindor is UP and Slytherin is La Salle, what is Ateneo? And what of the fourth house that's neither...?)

Ateneo's Ravenclaw, of course.

Then what's Hufflepuff's color?

UST.

Agreed, then. Some group will have to brainwash the said schools to think like they're houses of Hogwarts. And add magic to the curriculum!
