Monochrome interiors are timeless and rich Your decorating style could be midcentury, Art Deco or minimalist, but the boundaries of black, white and gray will allow for vibrant flourishes. Going monochrome doesn't mean abandoning color. Grays can range from sea-green and lilac hues to brown tones that resemble pebbles. For brighter colors, it's easy to combine pale or bleached floors with hits of natural greenery. Writing in The Wall Street Journal, Interior stylist Hilary Robertson says that best of all, the decor is remarkably simple. You won't be seeing red from color decisions. No more figuring out how the pattern on an upholstered chair will go with the color of the walls. With a limited palette, you can mix pieces from different decades, add patterns and layer textures. Robertson says it all works. In her farmhouse, Finnish interior stylist and product designer Annaleena Leina-Karlsson makes no concession to "country style." Like the photographs on her blog, Annaleenas HEM, she has applied a simple but sophisticated, mostly white formula to her living room. It has matte white walls and gloss-white painted floors. The scheme offers an effective way to show off the bold geometric accessories she designed. They include a long, rectangular gilt- metal box light that hangs across the ceiling and the gilt-metal inverted V, which serves as both sculpture and magazine holder on the coffee table. Her wipe-clean, white-leather IKEA sofas are practical for a space that houses five children.
