The Colorblind Video Adjuster app focuses on people with color issues in their vision like red-green or blue-yellow deficiency.

You can create manually a filter setup and apply them to images and videos with the intention to make some things visible, that aren’t for you.

The filter setups can be created in two ways.
First with the camera view of the app. Open it and point it in something you normally can’t see, then play around with the filters until the objects that are invisible to you become visible. After that save the filter setup and apply it later into your images and videos.
The second way to create a filter is through images of the Ishihara colorblind test. Go through the images with numbers, and again adjust the filter setup until the numbers become visible to you.
With a three finger tab on each screen, you can activate a short description of the functionality of it.
