The object of the invention is to provide a colorant composition for skin cosmetics, that can provide a natural texture while retaining hiding power, a foundation containing the same, and a method of makeup application. A colorant composition for skin cosmetics of the present invention is characterized in that the colorant composition, which contains nonwhite coloring materials, does not contain a high refractive index white pigment, and when the spectral reflectance of the colorant composition is measured under the below-described measurement conditions, the minimum spectral reflectance on the white ground in the wavelength range of 630-700 nm is 75% or higher, and the Y value on the white ground is in the range of 25-65 (Measurement conditions) A colorant composition is dispersed in nitrocellulose lacquer, the concentration of the colorant composition is adjusted so that the spectral reflectance on the white ground of a black and white hiding test paper at the wavelength of 400 nm is 10±2%, a black and white hiding test paper is coated with an applicator having a 0.101 mm clearance, and the spectral reflectance is measured with a spectrocolorimeter.
