I will go on record to say that I hate the look of all white Christmas decorations. The same goes for white and silver or ice blue and white. I find this look cold, sterile, lifeless, and creepy. White is not the only choice if red and green do not work in your home. Carolyne Roehm has wonderful examples of non-traditional Christmas color combinations that are elegant, sophisticated, Chinoiserie, and not afraid of color.
Blue and white is wonderful-but use the beautiful blue and white of Chinese porcelain and cobalt blue glassware.
Caroylne Roehm's living room is a great example of using color with the green sofas, blue and white porcelain, and elegant tree and gifts.
Red flowers with blue and white Chinese porcelain are stunning. My favorites are red roses, amaryllis, and carnations.
