PURPOSE:To produce a colored flaky metallic oxide having clear color and improved malleability and ductility, by coating the surface of a flaky metallic oxide or a precursor thereof with an oxide different from the oxide or a precursor thereof and calcining. CONSTITUTION:The surface of a flaky metallic oxide or a precursor thereof is coated with a metallic oxide different from the metallic oxide or a precursor thereof by immersion method. Successively, the coated flake is calcined to give a colored flaky metallic oxide which comprises compound oxide of plural metallic oxide or a solid solution and has 0.1-3mu average thickness and 1-100mu average size. Magnesia, zinc oxide and alumina are preferable as the flaky metallic oxide and hydrolyzates such as metallic hydroxide, metallic chloride, metallic alkoxide, etc., are preferably as the precursor, respectively. Oxides of V, Cr, Mn, Fe, Co, Ni, Cu, Mo, Cd, Pr, etc., are used as the metallic oxide to be coated.
