Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an alumuinum material and an aluminum alloy material with a gray composite film stable in coating material, capable of stable production and further capable of obtaining a gray pigmentation material having less blueness and low croma, and also to provide a method for producing the same. SOLUTION: An aluminum material or an aluminum alloy material is formed with an anodically oxidized film, is thereafter pigmented into deep bronze by an electrolytic pigmenting method and is further subjected to electrodeposition coating by using a translucent coating material of pale yellow to pale red series containing 0.01 to 0.5 mass% white pigment with a grain size of 0.1 to
