Chromatic Vision Simulator Status

"Chromatic Vision Simulator" makes simulated images of each color vision type from built-in Camera or Photos and shows you how people with specific types of color vision sees the world in real-time.  People with different types of color vision deficiency perceive colors differently.  “Chromatic Vision Simulator” is a color vision simulation tool which simulates the color vision of color vision deficiencies.  Color deficiencies are the inability to tell differences between some colors other people can easily distinguish.  Such color deficiency can be classified into three major categories: protanope / Protanomal, Deuteranope / Deuteranomal and Tritanope / Tritanomal.  This software is developed by Kazunori Asada (Ph. D. medical science and Ph. D. media design), based on the research in color science.  These color visions are predictable by calculating working of the cone cells that perceives the color to some degree.  For example, individuals diagnosed as Protan or Deutan cannot perceive differences between red and green, and pink and cyan.  About 5% of men have difficulty distinguishing red and green, or recognizing dark red.
