PURPOSE: A gold, silver and copper color gilding method of a three-dimensional ceramic material using low temperature plasma is provided which is capable of gilding pure gold, silver and copper colors on the total surface of the material made of ceramics in an inexpensive and non-polluting manner. CONSTITUTION: The gold, silver and copper color gilding method of a three-dimensional ceramic material using low temperature plasma comprises the steps of putting a gilding sample into a vacuum chamber of a PA CDV(plasma assisted chemical vapor deposition) equipment and forming a certain vacuum in the vacuum chamber of the PA CDV equipment using a vacuum pump; injecting TiCl4 and N2 gas into the chamber in a certain ratio at a certain temperature; forming plasma by applying a pulse voltage of DC 400 to 1000 V into the chamber; and ion depositing the sample in the chamber, wherein the ratio of the sample gliding to the injection gas is maintained to 1 m¬2/1.5 mL in the TiCl4 and N2 gas injection step, wherein gliding color is controlled to pure gold and pure copper color on the gliding sample according to injected gas amount and temperature, the gliding sample is glided in pure silver color when TiCl4 and C2 are injected in the TiCl4 and N2 gas injection step, and wherein a thin film is formed on the surface of the gliding sample as TiCl4 in the chamber is being separated into Ti¬+ and Cl¬- ions and Ti in the chamber is being bonded with the N in the ion deposition step.
