In my living/dining great room, I have very traditional colors because the room is all wood with yellow and green colors (very hobbity or Rohan feeling room to me!). The colors I decorate with for Christmas are darker than red and green; they are more of a cranberry red, hunter green, and gold accents. My library has dark blue walls, so when I decorate in there, it is with blue and white to make it look all wintery. My spare bedroom has green walls about the color of Arwen's coronation gown but more sage-y. It is decorated with LOTR and fairies and unicorns and dragons for my nieces and nephews (they love it!) For that room, I have a little white tree prelit with pastelly lights, and I use ornaments that have colors such as blues, greens, lavenders, and pinks with silver. It is very pretty, like a frosty garden in December. I don't really decorate my master bedroom, bathroom, or kitchen (except with kitchen dishes and teapots) too much- my house is a tiny cottage and decorating three rooms is more than enough for me!
