For a more relaxed atmosphere, you can find colors from whites, ivories and creams to pastel shades of green, blue and pink. Also look into choosing a fabric that matches other fabric colors in the room. As opposed to the more sedate, "sleepy" soft tones, don’t be afraid to venture onto the "dark side" and choose a darker and heavier fabric for your headboard. Darker fabrics work very well in a larger master bedroom that already is quite dramatic or romantic. Deep blues, magentas and greens can be very effective for getting this effect.
Create a nautical decor - deep blue and white which are reminiscent of the seas make for an inspiring nautical decor combination for the master bedroom. Use this colour combination for the linen, the furnishings, the upholstery and even for the wallpaper. An inspired idea would be to use the combination in stripes for the ceiling instead of in the wallpaper.
