Dull objects are things that lack shine, luster, or sharpness. They typically have a flat or muted appearance, lacking in brightness or interest. Examples include dull knives, worn-out pencils, and faded fabrics.

Coal is generally dull in appearance, with a matte or non-reflective surface. It typically has a dark, black color and doesn't have a shiny or metallic lustre.
The shininess or dullness of an object is determined by how well it reflects light. Shiny objects have a smooth surface that reflects light uniformly, whereas dull objects have a rough surface that scatters light in different directions, appearing less reflective. Materials like metal tend to be shiny, whereas surfaces like fabric or paper tend to be dull.
Dull dark objects absorb more light and heat energy than bright shiny objects, which reflect more light. The absorbed light energy is then converted into heat, causing dull dark objects to emit more heat. Bright shiny objects reflect a greater portion of incoming light, so less energy is absorbed and emitted as heat.
