Abstract |
The purpose of this study is to analyse the color perception characteristics in senior housing through the quantitative analysis of correlation between interior lighting and color. We executed subjective evaluation experiment of the color/lighting with Mock-Up after analyzing the visual variation of a senior people, along aging. We used the color differences decreasing method that can calculate a distance between two points in Munsell color space in order to evaluate color differences between the color that testee recoded with the lens filter and the base color of the ceiling, wall and floor. 1. As a result of color shift analysis using the color differences decreasing method, color difference between base color and object color was higher with lower illuminable. And the difference of color shift between two lens filters was low with higher illuminance. 2. In case of 850lux daylight color condition with color temperature higher than 4500K, color difference from base color was higher with YA3 lens filter than Y2. And there was no big difference between Y2 and YA3 in case of bulb color with less than 3500K color temperature. 3. In case of Y2 lens filter(40~50 age), it's better to keep the illuminance in 500lux with warm lamps(3500K), and in case of YA3 lens filter(60~70 age), color shift could be reduced if illuminance is higher than 850lux with daylighting lamp(4500K). |
