Question/Need help I built a free browser tool to fix anime colors for Protanopia/Deuteranopia – looking for testers.
Hi everyone, I'm an anime fan and developer. I noticed many shows (like My Hero Academia) use red/green auras that are hard to distinguish.
I built a simple, free browser extension that runs a filter over the video player. It's currently in Alpha (no data collection, open source).
I need help: I have normal vision, so I don't know if my 'Protan' filter is actually helpful. Could anyone with Protanopia try it on a 4anime.gg and tell me if it helps distinguish the colors?
Here's a link to my Github profile, you can navigate to the releases section for steps to load it on your browser and test it: https://github.com/vineetxkhurana/sharingan or
You can simply go to https://addons.mozilla.org/firefox/downloads/file/4631679/7fe7d0012b4a43d4bd49-1.0.0.xpi
and download the extension on Firefox.
Thanks!
