PURPOSE: A transparent color coating method of metal is provided which is capable of improving transparency and obtaining the same extent of weatherability and stability as in electrodeposition coating while using dyes instead of pigment. CONSTITUTION: The transparent color coating method of metal comprises a process of homogenizing a mixture of the grinded resin and the dyes powder as injecting dyes powder finely pulverized into lipophilic grinded resin easily bonded to dyes after performing pretreatment process, thereby covering the grinded resin with the dyes so that the dyes are encapsulated; a process of agitating the mixture by mixing epoxy resin having the same cation or anion series as in the grinded resin with pure water in a mixing ratio of about 1:2 to 4; a process of injecting the encapsulated dyes into a mixed liquid of the epoxy resin and the pure water so that the encapsulated dyes are in the homogenized state; and a process of coating the encapsulated dyes on the coating object according to electrophoresis by impressing the anode or the cathode to the encapsulated dyes, the epoxy resin and the pure water and impressing the anode or the cathode to a coating object.
