Simulates different types of color vision deficiency (color blindness) with differing levels of severity.
In addition to the functionality of the display filter "Color Vision Deficiency", this plug-in also simulates color weakness, not just complete color blindness and allows to save the resulting image.
At a severity level of 1.0, it simulates dichromacy, i.e. the complete absence of the relevant color receptor:
The plug-in takes an RGB* image, and simulates for the active layer how a color-deficient viewer would experience it. The result is saved in a new layer.
Currently, the plug-in appears under the top-level menu "Python-fu/Effects/Color Vision Deficiency".
