Abstract

A method for determining color combination, according to an embodiment disclosed in the present document, may comprise the steps of: obtaining target color information corresponding to a target color; generating color combination information corresponding to at least one color combination including at least one specific candidate color from among a first candidate color to an nth candidate color; estimating at least one color combination prediction reflectance by referring to the color combination information; comparing a target color measurement reflectance corresponding to the target color information with the color combination prediction reflectance; and determining, as optimal color combination information, specific color combination information corresponding to a specific color combination prediction reflectance that satisfies a threshold reflectance condition set on the basis of the target color measurement reflectance from among the color combination prediction reflectances.
