【 摘 要 】

Safety is one of vital aspects of liveable built environment. Designing a safe built environment requires comprehension regarding people's activities in that environment as well as their characteristics and abilities linked to those activities. People with various characteristics and abilities might use different methods and/or need different facilitations for performing activities, even when performed activities are similar. This paper presents how important comprehending characteristics and abilities of people in terms of visual sense is to color applications expected to support safe mobility in built environments. Colors in built environment have various functions. One of these functions is to provide visual information for identifying and navigating the environment. Color combinations enabling identification of built environment for fully-sighted people might be different from those of individuals with visual impairment. Conspicuous color combinations for fully-sighted people are not necessarily distinguishable for individuals with visual impairment having reduced functional vision. Building codes in Indonesia have included colour contrast as a requirement supporting safe mobility of people with visual impairment. Some public facilities in Indonesia have applied color combinations based on this requirement. However, this requirement is normative and vague; its applications are open to broad interpretation, which could lead to the occurrence of hazardous settings for mobility of people with visual impairment. The requirement needs more detailed descriptions established by utilising reliable measurement methods entailing comprehension of characteristics and abilities of people with visual impairment. Detailed descriptions will enable appropriate applications of colors supporting safe built environment for people with and without visual impairment.
