Color is a strong and integral part of both our natural and built environment. People experience color in different ways and in different settings often reacting subtly or overtly to its impact. In particular, people in healthcare settings who are vulnerable, healing, or aging have been understood to be influenced by colors used in interior design. It is not surprising then that a fair amount of research and inquiry has been undertaken on the use, role, myths, and impact that color can have on people in healthcare settings. By learning from these studies and applying the knowledge gained about the role that color plays in healthcare environments, designers can create spaces that better meet the needs of patients, staff, visitors, and other users. In addition, some of the misunderstandings and myths about color in healthcare environments can be cleared up to clarify what really does or does not impact people in the context of the built environment.
