About this app

Simulate colour blindness arising from the lack of red, green or blue light receptors.

The colour transformations are applied directly to the camera stream. Switch between different colour blindness modes to see which colours can no longer be distinguished.

Supported colour blindness modes are:
* Protanopia: complete lack of red light receptors
* Deuteranopia: complete lack of green light receptors
* Tritanopia: complete lack of blue light receptors

The colour transformations use the method of Viénot, Brettel and Mollon, "Digital Video Colourmaps for Checking the Legibility of Displays by Dichromats", Color Research and Application 24, 1999.

This application is written in Python using the Kivy graphical framework: https://kivy.org/
