You have plenty of options with black and white color scheme. The decision depends on your taste and preferences. You may stay with grey, black, and white colors only, or you may add an additional color like red, green, or yellow. You may decorate your bedroom with solid surfaces only, or choose any ornamental theme you like: stripes, floral, geometrical, zebra, etc. If you like zebra, go with this theme. The only important thing here is to keep balance between colors themselves and between solid and ornamental surfaces. For a small room the preferences should be light solid colors mostly, with small ornamental spots. A large amount of zebra for example, may look annoying in such room - I would go with zebra shams and white throw there. If a room is a spacious one - you may have folded down zebra throw and black (or white, or grey) shams or whatever you like. Here are some black and white bedding samples:
For your bedding I would suggest white – it will create a beautiful contrast with the dark furniture. I’m not sure that black will work well on the dark bed. Another option is grey or cream color bedding. I think you can get an interesting effect with such colors: the contrast with the furniture will be softer and zebra accents would look more eye-catching.Window Treatment Suggestion
As for window treatment, it should complement your bedroom decor and work well for your needs. If privacy and light control are not your preferences, you may drape your window with window scarf only. I suggest you to decide on your bedding first, since it is focal point in any bedroom. Then it would be easier to choose window treatment’s style and color. Even black window scarf may look very elegant in black and white interior. Some black window panels and valances:
Or, you may hang colored scarf, if you choose to include an additional color in your monochromatic interior. But again, keep in mind the size of your bedroom and the fact that dark colors make the room visually smaller.
