Description

It'd be great to be able to simulate/view more types of color blindness. As I learn more about it, the more I want to be able to design with accessibility for this in mind, especially since I do not suffer from any color deficiency, I find it hard to understand and visualize how I can best design with this in mind. The current Preview modes help, but I would like to see them go further.

Currently QGIS supports:
Protanopia
Deuteranopia

I'd like to see these added:
Protanomaly
Deuteranomaly
Tritanopia
Tritanomaly
Achromatopsia

I've attached an image from the above-linked Wiki page that shows color scales which indicate how each deficiency skews perception of color.
