title: [Study on the aging influence on the recognizability for colored targets--black and color].
abstract: Recently spaces for the aged have become more wide spread as the population of them has increased. Most of the spaces, however, are originally provided for the young and, accordingly, can not be considered preferable environments for the aged. From this point of view, the authors aimed at the visual environments for the aged and carried out experimental research on the influences that aging gives to recognizability for colored targets, for the purpose of providing a preferable visual environment for the aged. The results show that the recognizability for colored targets declines drastically from about fifty years old, as just as the recognizability for uncolored targets. Moreover, the results show that, although the recognizability of the young is considerably influenced by differences of the illuminance and color of the target surfaces, aging made the recognizability less influencable by these differences.
