The present invention is directed to a light-transmitting color film comprising oxides which have high chemical resistance and excellent light-absorption effect, making them available in a wide color range; a method for producing the same; and a coating solution used for forming the color film. In the light-transmitting color film comprising an oxide of an element which serves as a network former and oxides of transition metal elements serving as coloring components, the element serving as a network former is at least one selected from Si, Al, and B, and the transition metal elements comprise Cu, Mn, and Ni; and the two types of oxides form a complex oxide. Moreover, a method for producing the light-transmitting color film comprises: coating on the substrate a coating solution for forming the color film which contains at least one alkoxide of elements selected from Si, Al, and B which serve as network formers, and as coloring components, transition metal salts comprising at least Cu, Mn, and Ni, and at least one organic compound having a functional group which can coordinate the transition metals; and thereafter firing the substrate. |
