Sheen refers to a soft glow or luster that reflects light, often seen on surfaces like polished metals, glass, or certain fabrics. It can enhance the visual appeal of an object, making it appear more vibrant and attractive. The term is commonly used in art and design to describe the quality of light on surfaces. In the context of materials, sheen can vary from matte, which has no shine, to high gloss, which reflects a lot of light. Different finishes, such as those found in paint or varnish, can create varying levels of sheen, affecting how colors appear and how surfaces interact with light.
