No.  A colloid is a material suspended in a medium with a different phase.  But
if you want to specify what the state of the material and the medium are, you
have to use different terms.  For instance liquid in gas would be a fog, gas in
a liquid is foam, liquid in liquid (ie butterfat in milk) is an emulsion.  And
solid in a liquid is a sol.  So Colloidal silver is specifically a sol, a solid
suspended in a liquid.
