Art Nouveau are two types - decorative and constructive. In the first case of paramount importance the beauty and elegance of all the details. Furniture decorated intricately carved, forging, bead embroidery and leather inserts. In the second type, the main thing - is its functionality.
The color palette of the interior - a light, slightly muffled. For painting the ceiling and walls, choose coffee, pearl gray, beige, ivory, light yellow, silver, purple. And shades of textiles in the room should be combined with the color of furniture, and the overall color scheme of the room.
On the floor lay parquet (in the modern interior it can be replaced with laminate) classic "herringbone" or squares, or lay out of the same patterned parquet coating resembling fancy weaving the stems of plants. On the floor, lay a soft carpet with floral ornaments.
As decor often used floral motifs, images of butterflies, dragonflies and birds. They decorate picture frames and paintings, lamps, mirrors and stained-glass windows, as well as wallpaper, draperies and textiles.
Original and unique interior will add items decorated with artistic forging. This can be fireguard, stair railing decor or furniture with smooth lines florid imitating the leaves and stems of plants.
Modern Nouveau is not so expansive, you just bring some of its elements, and always remember the smooth lines and asymmetry. However, this requires large interior spaces, so the usual city apartment to create an organic space in a similar style will be difficult.
