Abstract:To explore the characteristics of the color environment required by the elderly in the indoor space,and then propose the relevant strategies for the design of the space color environment suitable for the living and activities of the elderly.Based on the physiological characteristics such as the perception of the elderly,the characteristics of the color environment in the indoor space are analyzed,and the actual cases are analyzed.The visual ability of the elderly declines with age,and presents the physiological and psychological needs of the spatial color environment.Using the physical and psychological attributes of color,it can create a positive and optimistic space for living and activities for the elderly.

除此之外,老年人对目标与背景之间的辨识能力会随年龄增长而减弱。贝尼罗(Beirne R O)等[6] 通过调研发现,年龄增长会导致人眼对目标与背景的对比敏感度下降,而且这种下降速度随年龄的增长而加快。如果把人眼获得可见度水平能力以20岁作为研究基准,为保持同样的目标可见水平,到60岁以上时,目标和背景区域的色彩对比与光环境应区分非常明显,以满足该年龄段获得同样可见度水平的对比度。人眼对颜色的辨别能力从青年时期就开始逐渐减退,对蓝、绿色的辨别能力明显下降,但对红、橙、黄色辨别能力没有明显变化。图1为日本学者吉田[7] 在1994年模拟了人眼水晶体变黄后所看到物体颜色的照片,其中编号1为模拟新生儿水晶体所拍摄的照片;编号2为模拟53岁中年人水晶体所拍摄的照片;编号3为70岁老年人水晶体所拍摄的照片。正如照片所呈现的,老年人对蓝绿色的区分能力明显降低。
