초록

Personalized makeup is preferred based on individual skin color diagnosis. In accordance, the need to diagnose skin color accurately is required. Skin color varies across different body locations and therefore inaccurate to measure skin color. For these reasons, human skin color is hard measure as a single color value. Therefore, this study investigated how to classify the tone and brightness of human skin by hue than to measure the skin color. Hue is easier for non-professionals to answer and has a wider choice than warm and cool based skin color. In this study, detailed classification of skin colors was attempted using skin color specimens and actual facial images. Based on the PANTONE SkinToneTM Guide, and real skin images, the skin was classified in terms of six hues of Reddish / Yellowish / Orangish / Greenish / Bluish / Purplish. Considering that skin color can be explained by relative values, the measurement data was converted to a difference (delta) from the average value. In skin colors, Redness (a*) and Yellowess (b*) were calculated by classifying each of them into two large categories and to clearly distinguish Lightness (L*) and Chroma (C*) from the tone graph. ∆a*(Redness) and ∆L*(Lightness) are calculated as differences from average value. In the same way, ∆b*(Yellowness)-∆C*(Chroma) was also calculated to explain the hue classification. We also identified that Korean skin color is divided into yellow, reddish, and orangish and the relationship with ∆b* and ∆C* values of CIELAB.
