To a great many people the full moon is romantic.

To some it is when the freaks come out, or just an excuse to act crazy.

For Remus Lupin the moonlight was something to dread. For it caused his painful transformation from man to werewolf. From mild mannered wizard to a vicious monster.

But for Nymphadora Tonks-Lupin the full moon causes her pain. She has to watch her husband transform and even before that he will attempt to push her away. At the full moon Tonk's hair is never the bubbly pink but a dull dirty blonde or dark brown.
