Abstract
As to the people who tend to staying in their own community of the elderly, "aging in place" has appeared as a residential concept in the recent years. The current housing and its facilities, however, are mostly not in a condition enough to support the senescence of the elderly. The Bathroom is an indispensable space related to the quality of everyday life, as well as a space with a high risk of safety accidents. This study aims to find the criteria of bathroom color design for the elderly and their cohabiting families. Survey research followed by literary review were conducted, and the subjects groups were classified into the old ones aged from 65 to 85, and the young ones aged from 20 to 40 answered the questionnaire with the printed images of 3D modeling composed of four analogous and eight complementary color schemes by R, Y, G, and B colors and Vp-, Dp-, and Dl-tone. The results are as follows: (1) Analogous color schemes of R and G colors were preferred in both the elderly and the young adult groups, while B color scheme was least preferred by the same; (2) Both the elderly and the young adult groups preferred 'R/Vp-G/Dp' complementary color schemes; and (3) The elderly group preferred 'R/Vp-G/Dl-G/Dp,' while the young adult group favored 'G/Vp-R/Dl-R/Dp' complementary color schemes for the safety bars in the bathroom.
