Sim Daltonism is a color blindness simulator. It filters in real-time the area around the mouse pointer and displays the result “as seen by a color blind person” in a floating palette.
Since there are many types of color blindness, Sim Daltonism allow you to choose the one you want to see. Available filters are:
- Monochromacy (complete)
- Monochromacy (partial)
Complete or partial inability to distinguish colors. This color blindness is pretty rare.
- Protanopia (complete red-green)
- Protanomaly (partial red-green)
Complete or partial inability to see using long-wavelength sensitive retinal cones making hard to distinguish between colors in the green-yellow-red section of the spectrum.
- Deuteranopia (complete red-green)
- Deuteranomaly (partial red-green)
Complete or partial inability to see using middle-wavelength sensitive retinal cones making hard to distinguish between colors in the green-yellow-red section of the spectrum. This is the most common form of color blindness.
- Tritanopia (complete blue-yellow)
- Tritanomaly (partial blue-yellow)
Complete or partial inability to see using short-wavelength sensitive retinal cones making hard to distinguish between colors in the blue-yellow section of the spectrum.
Note that I do not claim to have perfect or near-perfect color blindness simulation filters. This depends on correct screen calibration and other factors I cannot control.
This application is offered freely in an attempt to allow myself and other to ensure web and other designs are usable by color blind people.
What's New in Version 1.2
• Protanopia (most common color blindness) is now selected by default
