Abstract: An object to be achieved by the present invention is to provide a pigment which is comfortable and smooth to the touch in a coating, spreads well on the skin, for example, when used in a cosmetic material such as a foundation or an eye shadow, and exhibits good color development and gloss. A pigment of the present invention is a coated pigment formed by coating a surface of a flaky base material made of at least one metal or metal oxide with a colorant. The surface of the flaky base material has a coarse particle area fraction of 9% or less. Further, it is preferable that the flaky base material be at least one or more selected from the group consisting of mica, aluminum, alumina, and glass.
