I am not unsympathetic to the plight of that condition nor am I saying that it should not be solved. I am suggesting that the better and more practical way to solve this problem for the specific case of content consumed in a computing device is via a smart algorithm that is part of the OS itself than the owner of every piece seen through that device being co-opted into this. It is not an either-or to your crusade for the world to understand.
Shall we insist that every app and website provide voice assistance to visually impaired or to provide high contrast screens or do we make that part of the OS itself as a more pragmatic approach? We already have an answer to that one.
This is getting beyond the original intent and scope of the thread.
I am not insisting on anything, I am suggesting it would be to the benefit of any application or industry attempting to convey information via charts, graphs, way-finding, color-coding, etc in the physical world (print, floor tile way-finding, etc), digital world (graphs, charts, applications, websites) to take into consideration the limitations of colorblind users. I also agree, it would be great if MS, Apple, etc, included an option to "color correct" for the color blind.
If you think this is a crazy idea for industry to consider how to most effectively convey information, look around you; I bet you see a lot of pictograms.
Restroom doors, dashboard of your car, school zones, hazardous materials, waste bins, animal crossings, etc. Why? It conveys information to an extremely wide, nearly universally understood, manner.
The signs below is more effective and universally understood than writing out:
Explosive
Explosif
Sprengstoff
ระเบิด
Explozivní
