고령화에 따른 노인의 색지각 변화 특성

Abstract

The increasing population of elderly groups led to the aging society and as a consequence, the society is now predicted to become a super-aged society by 2050. That is why this study assumes that considering matters from looking after the elderly to improving convenience for the aged. As far as the study understands, the aged people’s visual and perceptual changes will make an important contribution to the special development of colors targeting the elderly. With the knowledge on how people aged over 65 find it more difficult to perceive colors and to distinguish a color from another of a different wavelength than the normal crowd, the study first aimed to look into how the elderly recognize similar colors and then, made an in-depth analysis in order to design a professional color program. Findings of the investigation on plastic color chips in 700 colors that the former Ministry of Trade, Industry and Energy had revealed that BG, B and PB which are included in a category of short-wavelengths are observed as these ranges of relative impressive color differences in how the aged would perceive colors. What the study had noticed was regarded as the yellow spot symptom and, the study found out that its result agrees to a theoretical fact that argues how the yellowed eyesight makes it hard for the aged to recognize the short-wavelengths. Now, the study suggests that when any relevant fields try to design special color programs targeting the elderly, they should limit brightness values of BG, B and PB to be intermediate and higher with low brightness values excluded and when it comes to chroma values, the development should focus on these color values that do not have low chroma values.
