We live in an amazing and colorful world! We are surrounded by a kaleidoscope of shades and colors — playful mosaic of light and shadow appears in every image and phenomenon. Green, obtained from a combination of blue and yellow, it is certainly the strongest color in nature and is rightly associated with the world of plants, which is its worthy representative. Green soothes, refreshes and even invigorates and no wonder people relax in the woods, among the greenery of trees, walking on the carpet of silky grass.
