“Monochromatic color schemes are derived from a single base hue, and extended using its shades, tones and tints (that is, a hue modified by the addition of black, gray (black + white) and white. As a result, the energy is more subtle and peaceful due to a lack of contrast of hue. Monochromatic color schemes may be considered boring unless there is diversity within the design.” – Wikipedia
Wikipedia is right – Monochromatic rooms can be boring. If I say, “grey room,” you might think, “That sounds really dreary.” But, if the grey color scheme is implemented correctly, like the room below, the result is stunning! Check out this room, as well as some other basically single colored rooms that I have included for good measure. Enjoy!
