"Personal Color Analysis for Korean Women’s (For women in their 20s and 30s)"
Min-kyoung Kim, KMK color Institute, Seoul, South Korea (Republic of Korea)

In modern society, it is becoming important to establish individual characteristics and unique personal identities. As a result, the Personal Color sector has already settled in the beauty and fashion industries. The purpose of this study is to analyze in personal color whether the color decided according to the fashion color is suitable for Asian people. Even if it is the same color, the color that matches the seasonal color tone is different. The purpose of this study is to analyze the colors that match Asian people 's favorite colors. If we research and analyze color preferences, we will be able to use trend color and personal color effortlessly in the future, The goal of this research is to investigate the internationally renowned, and Korean stars’ fashion and make up of K-POP.
In order to know the personal colors that Asian women' s are looking for, it is necessary to analyze the color of the four seasons and diagnose the color to match. The personal color diagnosis system consists of 1: 1 individual consulting and image-making through styles, images and beauty make-up through personal color analysis.

"Vision Experiment on Perception of Correlated Colour Temperature"
Youngshin Kwak, Ulsan National Institute of Science and Technology (UNIST), South Korea

The correlated color temperature (CCT) is widely used to describe the colors of display whites. The users can easily estimate the color of the display white based on CCT information. High CCT such as 7,000K means blush white and low CCT such as 4,000K means yellowsh white. However current CCT calculation method doesn't match with the visual appearance. Our study shows that CCT is highly correlated with warm-cool feeling of the white color, where warm-cool feeling is determined based on hue perception mainly. A series of hue perception experiments using the color stimuli near Planckian locus indicates that the orthogonal line from the Planckian locus in CIE u'v' chromaticity diagram can be used as the perception-based iso-CCT.

"Color Perception Specific to Facial Skin"
Yoko Mizokami, Chiba University, Japan

Skin color is essential for obtaining various information on our mind and body, such as health, age, and face impression. Therefore, we must have developed visual sensitivity tuned to skin. It has been suggested the existence of color perception specific to facial skin. For example, we have showed that sensitivity to changes in reddish (or hemoglobin increasing) direction of the skin is better than other color directions. Reddish skin looks brighter than yellowish skin even if they have the same lightness. These perceptions may link to the property of skin color determined by pigments of skin. Our results of international comparison also suggest that other factors such as ethnicities, environments, and cultures may also influence facial color perception.

"Image-based Measurement of Human Skin Color and Its Application in Cosmetics Field"
Kumiko Kikuchi, SHISEIDO Global Innovation Center, Japan

Understanding the skin color and skin color heterogeneity is important for many industries, especially in the cosmetics and esthetic fields. For objective measurement of skin color, the tristimulus colorimeter and reflectance spectrophotometer have been used for more than 50 years. In addition, various image analysis methods have been developed for quantitative evaluation of the skin color heterogeneity. Facial skin pigmentation is one of the causes of skin color heterogeneity and often affects perception of health and beauty. In order to characterize the individual pigmented spots within a cheek image, we established a simple object-counting algorithm and provided precise information on pigmented spots such as variations in size, color shade, and distribution pattern. In this presentation, some recent results of our research which relate to skin color and skin color heterogeneity will be introduced.

Dr.Kumiko Kikuchi is a research scientist at SHISEIDO Global Innovation Center, Japan. She received a Ph.D. in Engineering in 2016 from Chiba University. Her research interests lie in skin color, including skin color perception, development of measurement methods and spectral imaging of human skin.

"Chromatic Adaptation to Illumination"
Chanprapha Phuangsuwan, Color Research Center, Rajamangala University of Technology Thanyaburi, Thailand

I like to demonstrate that the chromatic adaptation takes place to illumination not to color of object based on the concept of the recognized visual space of illumination RVSI developed by Ikeda. The concept emphasizes the chromatic adaptation to the illumination that fills a space where a subject stay. A flow chart of this action is (1) to recognize a space, and (2) to understand the illumination in the space. Pungrassamee et al. (2015) showed that color appearance of physically achromatic patch depends on illumination of a space where a subject stay by using two rooms technique. Phuangsuwan et al. (2013) showed that the color constancy occurs even in a 2D picture if a subject recognizes a space in the picture and understands the illumination in the space. Recently we investigated the simultaneous color contrast for various devices; a paper, a projector, a display and a real scene (two-room technique) and explained the device dependent color contrast by the strength how much a subject transfer the color on devices to illumination. The same explanation was successfully applied to the simultaneous color contrast in after image and in a colored paper covered with a tissue.

"Best Colors for Safety Signs"
Kei Ito, University of Cologne, Germany

Signs that convey information about danger and disaster must be painted in the colors that all kinds of people can recognize unambiguously. Special care should be taken for the people with color blindness, low-vision, cataract, and aged, because they have difficulty distinguishing certain ranges of colors. Colors convey certain meaning, for example red for danger and green for safely. We therefore cannot “change” the colors for safety signs. However, by carefully adjusting the hue, saturation and brightness, colors can become much more distinguishable even for those people. The Japanese Industry Standard (JIS) for Safety Colors and the colors for the disaster information system of the Japan Meteorological Agency and TV broadcasters have recently been revised towards this aim. The concepts and backgrounds of these revisions will be explained.

Professor at the University of Cologne, Germany. He got his PhD for neuroscience at the University of Tokyo.

"Japanese Color Terms Denoting the Aesthetic Sense of Japanese Culture"
Kohji Yoshimura, Kansai Gaidai University, Japan

In different regions and countries, it is thought that there are some important colors exemplifying that area. In other words, in any region the people there can have some colors or color combinations that are commonly appreciated, valued, and employed in a certain way. However, the actual colors in this world vary significantly. There are really no colors and color combinations that are not found in other regions and countries. In Japan there are colors considered representative of the culture such as indigo (expressing ‘Japanese blue’), browns and mouse colors called the “forty-eight browns and 100 mouse colors” in literal English translation (in reality, more than 100 browns and mouse colors are included in these Japanese color terms), and red and white indicating celebration.

“From Vernacular to Divine Classics: A New Color Survey Approach”
Tien-Rein Lee, Huafan University, Taiwan
Vincent Ching-Wen Sun, Chinese Culture University, Taiwan

Surveys of color can be accomplished with a variety of ways, from questionnaire rating to self-painting target colors. Different survey methods aim to explore different aspects about “color,” which carries dissimilar meanings for variable research approaches. The present study suggests a new color survey approach which aims to find corresponding colors for a variety of items and reveal the color categories in them. We applied the basic color category investigation method of Sun and Chen (2018), which is based on the surveying procedures for basic color term by the World Color Survey (WCS) project. In our new color survey approach, we expand the survey to the color related terms found in ancient Chinese religious texts and also in western scriptures.
