Blue

Blue, the colour of the sky above and sea below, stands for tranquility. It is cooling, soothing and orderly. Blue brings comfort and serenity to our lives and is associated with royalty in some European countries. Blue is suitable for rooms to the south and in baths because it is associated with water. It is also a preferred colour for bedrooms, because it is known to induce sleep by calming the mind. To reduce stress in offices and treatment rooms, walls may be painted blue.
