Gabrielle was so used to her room changing colors that she had to take a moment to realize what Ginny meant. "Oh, it changes colors with my moods," She waved a hand negligently, "Fleur did it a few years ago."
The younger witch didn't mention that the only reason Fleur had felt it necessary was because at the time Gabrielle was having problems controlling her Veela, and that if she grew upset or angry enough to turn the room black, the doors would all seal until she calmed down. It would be counter-productive to worry Ginny, after all, and the problem was mostly under control.
"Schooling, mostly," Gabrielle slid her wand out of her sleeve and flicked it twice, once at the fireplace to shut it off from the outside, and once at her bed to open the curtains, "This is my last year at Beauxbatons and I am sure you understand how much there is to be done."
A thought occurred to Gabrielle, and she tilted her head at Ginny, asking lightly, "You graduated from Hogwarts this year, non?"
"Oh, bien sur," Another flick of her wand, and the far wall disappeared to reveal an extensive closet. "The nightclothes are on the far right, wear whatever you wish." The look on Ginny's face was cute and Gabrielle hid an amused smile, waiting to see the look on her face when she saw what Gabrielle usually wore to bed.
Actually, Gabrielle usually wore nothing at all to bed, but Ginny would be finding that out all too soon.
