Carlos Hernandez Matas created in 2011 three short films demonstrating the three main forms of color blindness: Deuteranopia, Protanopia and Tritanopia. There are many simulators for color blindness available online. One of them can be found right here on Colblindor: Coblis — Color Blindness Simulator.
Carlos explaines how he did those videos:
This is a program that retrieves images from a live video feed or from a video file stored in a drive and performs in real-time a color transformation to show how the video would be seen by one of the three kinds of dichromat color blind people. In this video, it’s shown the transformation for people with tritanopia.
