肌色は，健康状態や感情，人種などの情報を知る重要な手がかりとなる．Yoshikawa et al. (2012)は，平均明度が同じであっても， 赤みがかった肌は明るく，黄みがかった肌は暗く見える傾向があることを示した．ただし，実験刺激は日本人女性の平均顔と肌色であり，被験者も日本人であった．しかし，人間の肌色には多様性があり，人種などにより肌色の特性は異なる．本研究では，異なる人種の肌色に対しても，同様の明るさの知覚特性を示すかどうかを検証した．日本人女性の平均顔を用いて，コーカシアン，タイ人，アフリカンの平均的な肌色を再現した．各人種の肌色に対して色相角のみを変化させた評価刺激と明度のみを変化させたマッチング刺激を作成し，被験者は評価刺激の見えの明るさに一致するようマッチング刺激の明るさを調整した．明るさ知覚への色相や明度の影響を調べるためにタイ人，アフリカン，日本人に対しては明度を変化させた刺激も用意し，同様の実験を行った．その結果，いずれの肌色でも赤みがかった肌は明るく黄みがかった肌は暗く見える傾向となった．ただし，顔画像の明度が低くなると，この効果が小さくなることが分かった．
本研究は，色彩文化の視座よりイギリス国王ジョージ6世(Albert Frederick Arthur George, 1895-1952)の戴冠式に関する色彩計画について検討する.ブリティッシュカラーカウンシルは,これらのイベントの色彩計画を指揮していた.研究目的は,国家的式典とナショナリズムの表象としての伝統色との関係を明確にするためである.当時の写真,肖像画,風俗画や関連文献が一次資料である.特に,当時ヨーロッパ諸国で広まっていたナショナリズムの検討として,戴冠式の一環として行われた観艦式,園遊会,舞踏会も考察する.戴冠式で,色彩計画がどのように表現されていたのかを解き明かす.
Taoism is the only local religion in China, whose aesthetic philosophy takes up an important part in Chinese traditional aesthetic philosophy. In Taoism, cyan has been given a very special meaning, carrying Taoism’s core idea. Along the revolution of history, its aesthetic value has been influenced by the aesthetic ideas of the ancients. Thus, from the perspective of traditional culture, the particularity and representativeness of cyan make it valuable to be further explored in the field of modern fashion design.
The thesis suggests that perceptual impulses be supplemented by rational usage and the constant spiritual core be discovered under the versatile surface of design. Thus, it urges the emergence of new meaning and applications of cyan under globalization.
Peking Opera costumes are rich in color, and black is a spot color that becomes a certain type or a specific character. This paper attempts to explain the cultural significance of black in Beijing opera and its reasons for the traceability of black in Beijing opera.
The purpose of this study was to explore how adults and children perceive colors. During the 3-task experiment, first a questionnaire regarding subjects’ color preferences was prepared. Next, they were presented with 8 emotional facial expressions, each presented in 11 colors and were asked to select the most appropriate answer. Finally, they were presented with 11 color card boards(same colors as task 2)and were asked to rate how they feel about the represented color. Yellow was associated with happiness and blue with sadness(P<0.05).Children associated black with all the negative facial emotions(P<0.05).57.5% of the children associated white with unhappy, although white was a preferred color for bedroom for all the subjects(P<0.01).
Due to the diversity of Thai cultures, dialects, and environments that vary according to the regions, causing questions about the color names in Thai. 330 Munsell color chips were employed to obtain the color names used by 100 subjects(25 people per each region)using categorical method with monolexemic term. There was a similar mean number of color term usage in each region. Considering the consistency of the color name used by ≥80% of subjects found 12 color names, these included 11 basic color terms of Berlin and Key(1969)plus "Fa"(Sky)that was used by 100% of subjects for all region. There for, “Fa” might be added as the basic color name for the 12th of Thailand.
If the simultaneous color contrast pattern is covered by a white tissue, a vivid color can be perceived for the test patch. we measured the perceived color by the elementary color naming method. The relationship between the color appearance of colored paper and that of the same paper with tissue showed desaturation of color with tissue without change of the apparent hue. The relation of the color appearance of the colored surround with tissue and that of the central test patch with tissue, when expressed by the apparent hue angle, was very similar to the relation found by the two-room technique, implying that the tissue was caused by the perception of illumination over the colored surround perceived through tissue.
The simultaneous color contrast is a common subject in the study of color vision as it provides researchers with data from which they can speculate the visual mechanism for chromatic adaptation. In the study, however, people use different devices to present the stimulus pattern. It is possible that different devices give different data to draw different conclusions about the simultaneous color contrast. In this report the simultaneous color contrast is measured with five different devices, object mode, object covered with a tissue paper, display, projector, and two-rooms technique. Four surrounding colors, red, yellow, green, and blue were made same throughout devices. Apparent hue did not change much among devices but the amount of chromaticness of the central patch varied from 15 % to almost 70 % in the case of red surrounding depending on devices. We should not compare results of simultaneous color contrast directly if different devices were employed.
Color naming using 11 basic colors was conducted for 330 color chips of World Color Survey WCS by 60 Thai students of RMUTT in Patumthani, Thailand in an experimental booth of which illumination was white with illuminance 2644 lx. There were many responses beside the basic colors responded by the subjects. There were 25 color names beside 11 basic color names such as Fha(sky blue/light blue),Nue(skin tone),(indigo/dark blue)for example. But the most frequent response was “Fha” in Thai or “Sky”. We concluded that the color name “Fha” should be included in Thai basic color in addition to the eleven basic colors proposed by Berlin and Kay. We found no difference in responses between female and male.
100 hue test was conducted under a normal lighting with fluorescent lamps and under a spot lighting composing of three LED lamps with a deep hood to eliminate environment light. Fifteen subjects participated in the experiment. Each subject did 100 hue test with cataract experiencing goggles to simulate elderly eyes. All the subjects gave better score with spot lighting than fluorescent lamp lighting. Mean error score was 197 with the spot lighting, whilst it was 215 with fluorescent lighting to show that spot lighting can present a better lighting environment to elderlies than normal lighting that radiates light.
