“Chromatic Vision Simulator” is a color vision simulation tool which simulates the color vision of color vision deficiencies. This software is developed by Kazunori Asada (Ph.D. medical science and Ph.D. media design), based on the research in color science.
About 5% of men have difficulty distinguishing red and green, or recognizing dark red. Such color deficiency can be classified into three major categories: protanope / Protanomal, Deuteranope / Deuteranomal and Tritanope / Tritanomal.
Color deficiencies are the inability to tell differences between some colors other people can easily distinguish. People with different types of color vision deficiency perceive colors differently. For example, individuals diagnosed as Protan or Deutan cannot perceive differences between red and green, and pink and cyan.
These color visions are predictable by calculating working of the cone cells that perceives the color to some degree.
"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.
Fixed a bug that crashes immediately after displaying splash when used with iOS 9 or lower.

Actually really good
I’m color blind, and my daughter is color blind.
I first got this when she was younger to help her mother understand what our daughter could see. She has it installed on her iPad, so she can check whether the things my daughter does make sense.
The one improvement I would like is to embed an Ishihara, dot pattern test, which would allow you to adjust the gammas, until you can see the shapes, and then invert the adjustments to give folks a look at what the colorblind person really sees.
Additionally, once the color blind person has adjusted the gamma values to see the patterns in the dots. There could be a view port the user could use to have a better understanding of what those with normal color vision see. Personally, I’m not “blind” to red and green, but I see only fifteen to twenty-five percent of what a person with “normal color vision” sees. It might be fun to understand why people think things are beautiful.
Wonderful! A Picture Is Worth A Thousand Words
If your color blind and want others to see what you see, this is the app you want to use! Ever since I was a child, I’ve always suspected I was color blind. No one believed me because I can successfully guess the colors about 90% of the time. This wasn’t confirmed until I was 21.
Now that I have this app, I’ve used it with my wife, kids, friends and co-workers. Just recently, after taking an Ishihara Color Dot Test, I used this app to show the tester how I see the dots. Absolutely wonderful app!
It's really interesting to see what the world looks like to colorblind people. But could you add a way to import videos instead of just photos?
