Textures refer to the surface quality of an object, which can be felt or seen. They can be smooth, rough, soft, or hard, and they play a significant role in how we perceive the world around us. For example, the smoothness of a glass surface contrasts with the roughness of tree bark, creating different sensory experiences. In art and design, textures add depth and interest to a piece. Artists often use various materials to create unique textures, such as canvas, paper, or wood. By combining different textures, they can evoke emotions and enhance the overall visual appeal of their work, making it more engaging for the viewer.
