Color tone quantification device for glossy color, color tone measurement device for glossy color and color tone quantification method for glossy color

A purpose of the present invention is to provide a color tone quantification method for a glossy color, in which the correlation with the color tone of the glossy color visually perceived by humans isfurther enhanced. The present invention for achieving the above object relates to a color tone quantification device. The color tone quantification device comprises a coefficient calculation unit that calculates a coefficient calculated in consideration of a spatial distribution which is to be used to correct the chromaticity measured by a method including a specular reflection component obtainedby measuring the reflection light obtained by reflection of measurement light to an area of an object; a chromaticity calculation unit that calculates an effective chromaticity obtained by weightingthe chromaticity measured by the method including the specular reflection component with the coefficient calculated by the coefficient calculation unit; and an output unit that outputs the effective chromaticity as a stimulus v
