BALANCE OF LIGHT AND SHADOW. In many ways, the appearance of a living room is determined by how balanced light and shadow are in it. Therefore, proper illumination is very important. For example, for the convenience of staying in residential lighting, a multi-level layout of lighting fixtures is mandatory. Lighting also affects the perception of colors. THE CONTENT OF THE DECOR IS AT LEAST IMPORTANT THAN ITS FORM. In order to choose a decor that fits harmoniously into the interior, a good decorator should know how and what it is made of. After all, the content is invariably reflected in the form. For example, putting a flower pot on the window from material that is not resistant to fading, after a couple of months you can find it has lost its original color. DARK TONES - NOT ONLY FOR BIG ROOMS. A small room, dominated by dark tones, looks no worse than light. Conversely, saturated colors dominate the boundaries of space, diverting attention from its modest size.
