Colours are primarily composed of three properties - hue, brightness, and saturation, However, each property of colour is not independently visually recognised. Previous studies on saturation and brightness found that brightness was sensed differently depending on the degree of purity of the saturation; however, most of the psychophysical experiments used subtractive mixing. Therefore, fundamental research on colour perception based on display is needed. In this study, we conducted a psychophysical experiment and to investigate the visual characteristics of saturation and brightness based on a display with a self-luminous system. After selecting a certain brightness in the additive-mixed display, the experiment was conducted by adjusting the saturation of the main colours. Thus, by analysing the experimental results, we determined whether the results were the same as ones from subtractive mixing and whether the data are meaningful for the characteristics of colour perception. We also suggested future research directions.

When it comes to how to define history·culture streets, people think of the streets as street environments that would create local identity in association with this local community's particular historical and cultural resources as well as urban streets. In order to build such streets, any relevant fields first need to apply some original design based on understanding on historical and cultural resources. With Street of Gaya in Gimhae selected as a research subject, this study aims to look into components and color characteristics of the history·culture street and finds ways to create other streets of that kind. As a frame to understand the history·culture streets, what this study would come up with is considered significant in that it helps the value to be re-recognized and promoted. In order to achieve the research goal, the study (1) extracted components of streetscapes referring to relevant previous researches and then, (2) analyzed a current status of these components of Street of Gaya via field investigation. (3) The study examined color characteristics of each of the components. Findings of the research are summarized as follows. (1) From a comprehensive point of view, the study categorized and subdivided the components of the history·culture street into nonphysical and physical elements. (2) After analyzing the current status of the components, the study learned that Street of Gaya basically consists of historical and cultural remains and sculptures as well as street facilities. (3) Results of the color investigation reported that the plan on designing of Street of Gaya had been processed with a focus laid on harmony of historical remains and cultural remains which are told to be natural components. However, the study also figured out that as long as relevant fields want to create different identity in each section and to efficiently deliver information, they should first prepare this smart design system to integrate each pieces of a streetscape as a whole.

The objectives of this study is to develop an adaptable digital wall model whose color can be changed dynamically according to the identified emotional state of a user. This study addresses how to capture a specific user's emotion through the web and use it for modifying VR model mainly for color adaptation. This adaptation process of a VR model consists of three phases: 1) identification of the user's emotional state projected onto the list of emotional keywords 2) translation of those captured emotional keywords into a pertinent set of color coordinations, and finally, 3) automated color adaptation process for the given model. This process derives an on-line viewer's emotional state, which can be utilized to find a new color scheme reflecting the identified emotion.

The perception of a fashion product may vary depending on the texture and color of its material. Additionally, the product may appear differently in person versus on a digital screen. Therefore, in the present study, we sought to investigate the differences in visual sensibility evaluation between materials in person and on digital screens. In this study, three pairs of visual sensibility adjectives were tested for 60 samples selected as fashion materials. Fashion materials were divided into colors, embossings, and visual clarity categories. Results showed that each color had the same sense during in-person and digital evaluation. In terms of visual sensibility according to embossing, both in-person and digital evaluations of materials with embossings were found to have the same visual sense, whereas those without embossings looked different between in-person and digital evaluations. Assessments based on visual classification showed that both in-person and digital evaluations had the same sensibility. This study is meaningful in suggesting that when evaluating the visual sense of fashion material, the sensation for the digital screen versus in person may be different in some cases.

This study was aimed to characterize the color of cotton fabric dyed with three different natural resources such as persimmon, citrus, and brown algae and to propose new trend color themes for fashion color planning for newborn and toddler wear. A variety of color shades by dyeing cotton fabric with persimmon, citrus, and brown algae respectively was obtained and each color was also determined if it could be matched with one of Pantone TPX considering authorized color trends for 2016 Spring/Summer. Finally a group of new trend color theme for 2016S/S newborn and toddler wear were proposed for naturally dyed cotton fabric. As results, the three natural dyeing resources gave color gamut with hue ranging from Purple Blue to Green Yellow and with tones including pale, light grayish, soft, grayish, and dull by their single and compound dyeing. A total of 23 colors matched to Pantone TPX were considered for the fashion color planning by natural dyeing. The selected natural colors were grouped as three different color ways and thereafter the color ways were differentiated in terms of representative color sensibility by using subjective evaluation. Finally three characterized color themes were proposed as 'Serenity', 'Juicy', and 'Fancy', each of which has tried to express differentiated feeling of each natural resources for dyeing, to follow up to global color trends, and to contribute to newborn and toddler wear's own requirements and marketability. These results suggest that natural dyeing colors could be applied into fashion color planning in current fashion industries in order to produce more sensible and emotional design of fashion goods using natural dyeing.

When thinking about the essence of color, green is the image that is settled on the plant itself, and it is also the color shining by the sun. Physics tries to explain green of plants in the correlation of sun and moon, and the history of art contemplates how it is expressed on the canvas. The film attempts to represent a realistic green using camera or computer specific to the medium. Many color theorists who explore the essence of color do not trust the mechanical and reductive scientific colorism that began in Newton and seek a completely different way of exploring in psychology and aesthetics. Like Goethe, who opposed Newton, they do not distinguish the human as subject and the color as object, but focus on the internal grounds of the relationship between subject and color. The representation of color in film is a combination of physics and art. Film color can be expanded to the spiritual dimension beyond the previous emotional and aesthetic, even beyond the physical and mental domains.

The plastic optical fiber has been previously known to have the limits in fabrication and care, due to its lack of flexibility and durability. Recently, an innovative technology of 'water-resistant & flexible optical fiber', in which the surface of etched POF(i.e., plastic optical fiber) is to be coated with a type of synthetic resin, has been developed. In this study, the post-treated POF-based flexible textiles were evaluated in terms of luminance, physical visibility and perceived visibility, according to the fabric lengths and colors of the light source. The POF-based flexible textile with 10cm fabric length and green light source appeared to show relatively higher illuminating effects. The maximum distance for perceived visibility of the POF-based flexible textiles was found to be 100m. Therefore, the results of this study are expected to be utilized as a fundamental for the further studies to develop the digital color clothing with application of POF-based flexible textile.

Next generation displays show a trend of evolving from the display device environment (represented by existing televisions) to the mobile environment. The mobile display corresponding to the personal display is similar to a home theatre; however, they are advantageous because they are small and have a relatively lower weight. Therefore, the display industry has an interest in diverse product applications of displays, reproducing more accurate colours, and offering improved image quality from display devices of various sizes. To address these interests, a psychophysical experiment was conducted in this research. The experiment compared the size of the colour stimulation corresponding to foveal vision by gradually increasing the lightness of the background. This was based on the assumption of possible differences in colours being recognized by the lightness of the background and the size of the colour stimulation. Contrary to the results of previous studies, where the colours are identified more clearly as the size of the colour stimulation increases (assuming that the lightness of the background is not considered) here the results of the experiment showed that the attributes of the identified colours were different depending on the lightness of the background and the size of the colour stimulation. Based on the experimental results, it is possible to resolve errors in colour conversion that can occur when the input image is switched from a large screen size to a mobile size display, and to reproduce the colours more accurately and improve the image quality.

디지털 삶에서 인간들은 더 이상 보호막으로써의 건축 환경이 아닌 함께 상호작용 할 수 있는 감성반응 환경을 요구한다. 즉, 실내 공간은 사람들의 요구를 충족시키거나 사람들의 기분을 만족시키기 위해 건물이 마치 살아 있는 유기체처럼 쉬지 않고 변하는 공간이다. 그러나 건축공간의 물리적 특성의 한계에서 유동적인 감성반응 환경의 요구를 충족시키는 데에는 많은 한계점이 따른다. 그래서, 본 연구에서는 이러한 한계점을 극복하기 위해 디지털 환경을 이용한 가상공간에서 실행하였다. 이는 실제공간에서의 시행착오를 줄일 수 있을 뿐만 아니라 빠른 시간 내에 인간의 반응을 연구할 수 있다. 특히, 본 연구에서는 감성반응의 실내배색에 의해 실내공간에서의 디지털 벽면의 디자인을 가상공간에서 개발하여 거주자의 감성 반응을 평가하는 것을 연구 목적으로 두었다. 이와 같은 거주자의 감성반응형 환경 디자인은 미래의 디자인의 패러다임이 될 것이다.
