Online Simulator Shows You What Photos Look Like to People With Color Blindness



Approximately 1 in 12 men and 1 in 200 women suffer from some form of color blindness. Given those statistics, it might not be a bad idea for photographers to occasionally consider how their work is being viewed by those who can’t see the entire spectrum. And right on cue, a new online simulator from Etre is here to help.

The simulator will take any photo you would like to upload (given the dimensions are less than 1000 x 1000 pixels and the file size is less than 100Kb) and spit out a color blind preview of the image.

You can choose from three types of color blindness: Protanopia and Deuteranopia (both common forms of red-green color blindness) and Tritanopia (blue-yellow color blindness). Once you’ve uploaded the photo and chosen your particular genetic variant, the website will do the rest and show you what your color blind viewers are seeing.

At the top you’ll see an example we ran through the simulator. Top left is the original photo, top right as seen with Protanopia, bottom left as seen with Deuteranopia, and bottom right as seen with Tritanopia. Even if you never put the simulator to practical use, it’s quite interesting to see how your more colorful photos are being perceived by almost 4.5% of your audience.
