Protans are people with Protanomaly, a type of red-green color blindness where the red cones in the eye do not detect enough red light, but instead respond more to green light.
As a result, many colors such as green, yellow, orange, red, and brown may appear confusingly similar. People with color blindness often also confuse blue and purple, and see pink as a shade of gray or white.
When all red cones are missing the Protanomaly condition is called Protanopia.
Protans with Protanopia (also called red-blind) are Dichromats.
In this case the long wavelength sensitive cones (red) are missing at all. A protanope can only distinguish 2 to 3 different hues, whereas somebody with normal vision sees 7 different hues.
Protans with Protanomaly (red-weak) are Anomalous Trichromats.
This can be everything between almost normal color vision and protanopia. The red sensitive cones are not missing in this case, but the peak of sensitivity is moved towards the green sensitive cones.
From the Setup menu choose Protanopia.
The colors of the screen will now change. Screen colors are daltonized in real-time.
This is general preset for people with Protanomaly and you should now be able to distinguish more colors.
If you want more fine control you can buy Vision Pro. With the Pro version of Vision you can customize the Severity of your color vision deficiency and the Color adjustment applied to the screen.
The recommended Severity for Moderate Protans is 50-75%.
Move the Color adjustment slider as you like. For best color discrimination use the most left or right position of the slider. Values in the center have really small color correction.
Happy using of your new computer full of colors 🙂
One thought on “Strong Protan”
This was very helpful, before taking this test I did know I was color-blinded; however I didn’t know which kind of color-blindess I posses.
