온도감은 촉각과 시각에 의해서 느낄 수 있는 감각이다. 하지만 온도감에 대한 개념을 시각적 온도감과 촉각적 온도감의 개념을 함께 활용되는 경우는 드물다. 이 연구에서는 촉각을 통해 느끼는 온도감과 시각을 통해 느끼는 온도감에 대해 색채와 재질 특성에 따른 시각적 온도감의 관계를 알아보았다. 색채와 재질의 특성을 포함할 수 있는 샘플로 원단을 선택하였다. 15-16가지 종류로 Y계열, R계열, B계열, G계열 총 61개의 샘플로 실험을 진행하였다. 분석 방법은 Yellow, Red, Blue, Green의 색을 떠올렸을 때 느끼는 색에 대한 온도감을 분석한 뒤 각 색상별로 원단의 촉각적 분류 및 시각적 분류에 따른 시각적 온도감에 대해 알아보았다. 그리고 무게, 두께, 요철에 따른 시각적 온도감의 상관관계를 알아보았다. 그 결과 동일한 원단에서는 색 온도감에 따라 Cool과 Warm으로 느끼는 원단의 수가 차이가 났다. 그렇지만 원단의 분류마다 시각적 온도감은 다르게 나타났다. 특히, 얇은, 비치는 원단과 무광택 원단에서 두드러지게 나타났다. 무게, 두께, 요철과 온도감의 관계에서는 무게와 관련을 보인 원단 분류는 딱딱한, 무광택 원단의 분류이며, 두께와 관련을 보인 원단 분류는 얇은, 비치는 원단이다.

The experiment aimed at knowing the effect of physiology and psychology according to season on color preference. Two tests, one of the spring and the other of the autumn was conducted. Seventy subjects with normal color vision served as subjects. The subjects entered a bioclimatic chamber controlled at a temperature of $25\pm1^{\circ}C$, a relative humidity of $50\pm5\%$ and a light of 1000 1x. The subjects wearing white shirts and trousers sat quietly on a sofa for one our. Sensation from warm to cool colors might be possibly different individually Therefore, a subject asked to array 41 randomly placed cloth colors from very warm to very cool colors during rest quietly for one our. All subjects arrayed these cloth colors in the order from red through yellow and green to blue, which had the reproducibility. After rest, they were instructed to choose a single one out of 41 cloth colors, preferred by themselves, every 10min during one our 0-ring test were measured to red, yellow, white, blue, black, favorite color, and dislike color. Most subjects preferred warmer color in April than in December. Tympanic temperature was significantly lower in December than in April. Finger presser was significantly higher in like color than in dislike color but it was no significant differences between spring and autumn. The preferring the warm color in April toward summer when basal metabolic rate is decreased than in December toward winter when it is increased can explain that physiology reaction by load error between actual core temperature and set-point induces psychological reaction to pursue visual alliesthesia. Our present experiment revealed that the preferred color could be determined by the relationship between the internal temperature and its set point according to season. It should be emphasized that the alliesthesia was observed also in the realm of visual system.

Kruithof demonstrated the preferred combination of illuminance levels and color temperatures. However, as Benett pointed out, difference of themal variables in such preference may be expected. The purpose of this study is to clarify the combined effects of lighting conditions(illuminance, color temperature), operative temperature on the human physiological and psychological responses. In order to observe operative temperature change in preference of color temperatures for three illumination levels, three subjects were exposed to two different conditions of color temperatures of 2,850K, 4,200K and 6,850K combined with operative temperatures(OT) of $25{\sim}31^{\circ}C$ at 100~1000lx. Thermal sensation vote and comfortable sensation vote, brightness perception vote were reported in each experiment conditions. The following results were obtained : 1) When illuminace level was at 100lx in operative temperatures of OT $20^{\circ}C$, $25^{\circ}C$, $30^{\circ}C$, Color temperature affect not themal sensation but Warm-cool sensation. 2) Operative temperatures affect not brightness perception vote but visual comfort sensation vote, satisfactive sensation vote, warm-cool sensation vote and themal sensation vote.
