hex code for silver color or also silver is a metallic tone similar to gray, close to the appearance of polished silver.

The visual sensation often associated with silver metal is its metallic sheen. This cannot be represented by a simple solid color because the glow effect is due to the incidence of the light source in the material composition. There is also no way to reproduce metallic or fluorescent colors on a computer. In painting, an artist typically uses a metallic paint that shines like real silver. The color shown here cannot be considered silver, but it is the closest representation possible.
