What is Sim Daltonism?

Sim Daltonism can simulate the vision of many forms of color 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 colors
  • Monochromacy
  • Partial monochromacy

Note that the colors shown are only an approximation. Color 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 color blindness.
