ABSTRACT:
A metal plate is given an excellent decorative color by a multi-ceramic coating of a colored ceramic layer formed over the metal plate, the colored ceramic layer being made of at least one selected from the group consisting of nitrides and carbides of titanium, zirconium, hafnium, chromiun, niobium and aluminum and having a thickness of 0.1 .mu.m to 1 .mu.m ; and a transparent ceramic layer formed over the colored ceramic layer, the transparent ceramic layer being made of at least one of the group consisting of silicon oxide, silicon nitride and aluminum oxide and having a thickness of 0.1 .mu.m to 5 .mu.m. The depositions of the colored and transparent ceramic layers are effected by a dry process, and the order of deposition of the colored and transparent ceramic layers can be reversed.
