Do you have some kind of an accessibility tool for this? Maybe a whole screen filter that changes colors in a specific way so you can distinguish them?
No I don't. It's actually not a big deal in day-to-day life. People often go "But how the hell can you drive if you can't distinguish red from green at the stoplight?"... in reality it's more nuanced. As another comment already mentioned, perception varies across even among colorblind people. I find it hard to distinguish R/G if the colors are not fully saturated or in low-light situation. Also the brain knows that "red is on top" and "green is at the bottom" at the stoplight and thereby improves the contrast for me. ;-)
My comment was meant to raise awareness of this issue with the author of the tool. Many video games, especially the ones with some kind of HUD, minimap, etc. these days have a color-blind mode.
Yeah I’ve seen colorblind modes in a lot of apps. It is great for those affected. And probably not a huge hassle to implement anyway.
But I was curious if one needs to rely on the application developers to deliver a solution or if there was a generalized filter or whatever that would work always. Maybe like screen readers, those work fine if the app does not do something horrible. But with some help from apps, they perform much better.
