Reexamination of color vision standards

This report is a continuing effort to examine the FAA's color vision standards, focused on understanding how individuals with color deficiencies use color-coded information. First, literature about the effectiveness of color relative to achromatic visual cues was reviewed and synthesized. Next, several algorithms were developed to assess the effects of color for individuals with color deficiencies. Using a computational algorithm that simulates how color deficient individuals perceive color, the effectiveness of color in task performance was able to be calculated. By considering together the effectiveness of redundant visual cues and the perception of those with color vision deficiencies, a method is provided to assess the potential effects of color deficiencies in using color displays.
