Puzzle silver

Silver or metallic gray is a color tone resembling gray that is a representation of the color of polished silver. The visual sensation usually associated with the metal silver is its metallic shine. This cannot be reproduced by a simple solid color, because the shiny effect is due to the material's brightness varying with the surface angle to the light source. In addition, there is no mechanism for showing metallic or fluorescent colors on a computer without resorting to rendering software which simulates the action of light on a shiny surface. Consequently, in art and in heraldry one would normally use a metallic paint that glitters like real silver. A matte grey color could also be used to represent silver.
