Hufflepuff Common Room:Yellow the colour of warmth

"It is round and earthy and low-ceilinged; it always feels sunny, and its circular windows have a view of rippling grass and dandelions. There is a lot of burnished copper about the place, and many plants, which either hang from the ceiling or sit on the windowsills. Our Head of house, Professor Pomona Sprout, is Head of Herbology, and she brings the most interesting plant specimens (some of which dance and talk) to decorate our room — one reason why Hufflepuffs are often very good at Herbology.
