Description

Method for predicting color of cosmetics and service server using the same The present invention relates to a method for predicting the color of a cosmetic product that can predict the actual color of the cosmetic product from prescription information regarding the cosmetic product, and a service server utilizing the same. Makeup cosmetics refer to various products used to enhance facial beauty or conceal imperfections. Makeup cosmetics are used to highlight or correct areas such as the skin, eyes, lips, and cheeks. Generally, makeup cosmetics include foundation, eyeshadow, mascara, eyeliner, lipstick, blush, and concealer. In the research and development of makeup cosmetics, the color matching stage involves selecting a target color and adjusting the content of dyes or pigments within the cosmetic's components to achieve the exact same shade. During this process, the time required, cost, and quality of the color matching vary depending on the skill level of the person performing the mixing.
