Tools and Features of Sim Daltonism

Sim Daltonism can simulate the vision of many forms of colour blindness:

Red-Green

Deuteranopia (no green cones)
Deuteranomaly (anomalous green cones)
Protanopia (no red cones)
Protanomaly (anomalous red cones)

Blue-Yellow

Tritanopia (no blue cones)
Tritanomaly (anomalous blue cones)

All colours

Monochromacy
Partial monochromacy

Note that the colours shown are only an approximation. Colour blindness varies from person to person and the simulator cannot represent everyone’s vision. Many other factors can affect the results, such as the automatic white point calibration of the camera. Nevertheless, Sim Daltonism is a good tool to better understand colour blindness.
