Culture of Silver: Like black, silver is used as a color of mourning as well as a color of formality. Along with blue suits, gray/silver suits are part of the uniform of the corporate world. Dark, charcoal gray carries with it some of the strengh and mystery of black. It is a sophisticated color without much of the negative attributes of black. Lighter grays and silvers are similar to white. Gray/silver tuxedos are common for men at weddings.
