I’d like to share my finding over my Architectural career regarding color perception and safety, especially for the seniors and the elderly. Some extensive scientific and empirical research has revealed some new phenomena, psychology and safety issues in colors, and has also confirmed some previous theories. All of which has a daily impact on human behavior, safety and health. These are only some of my findings. (More to come.)
— The health and age of one’s eyes has a major influence on color.
— Aging eyes, ie: yellowed tend to absorb and scatter blue light.
— Pastel tones & cool hues are more difficult to see after age of 60.
— Aging eye can best discriminate reds, orange and some yellow.
— Glossy surfaces are difficulty for the aging eye.
— Cataract lens make color scheme with only Yellow, are hard to see.
— Blue, blue-green or violet color scheme may appear gray.
— Color contrast is the most important design aspect to emphasize.
— A simple contrast change of colors is beneficial for orientation.
— Contrast of hue: red and yellow, white and blue is excellent.
— Contrast of value (lightness and darkness) of same hue is good.
— All-White or neutral-toned bathroom are difficult to navigate.
— Contrasting wall paints is least costly and is safe and effective.
— Colors are best seen against gray rather than white background.
