Shading is a technique used in art to create the illusion of depth and dimension. By varying the darkness and lightness of colors, artists can make objects appear more three-dimensional. For example, when drawing a sphere, adding darker shades on one side can suggest that light is coming from a specific direction, making the sphere look rounder. In addition to art, shading is also important in fields like graphic design and animation. It helps to convey mood and atmosphere, enhancing the overall visual experience. Whether using pencils, paints, or digital tools, effective shading can bring a piece of work to life.
