@Awoo @applejack literally the only thing keeping me from using linux wholesale at this point is that there is absolutely horrible colorblind support.
the programs that do provide filters are either laggy as hell, super unwieldy to use (like needing to have a second monitor just to see what the first one looks like with the filter), or actually simulate colorblindness.
i don't necessarily have the money to commission a whole ass program that would drop a filter over your screen right now but it is something i'd eventually like to see happen.
the only package it seems was relatively good for colorblindness is gnome-mag but it's loooong been abandoned and doesn't work anymore, plus i have no idea if it technically actually worked or not.
just using monitor or GPU color correct isn't a very elegant solution either, because doing that shifts colors in total rather than just taking specific color ranges and either amplifying or desaturating them. if i try and boost reds, for instance, i end up with grays becoming slightly red too which windows' filter doesn't do. if it does it is way too minor of a difference to notice. maybe they're doing some black magic or something but Android and iOS colorblind settings do the same thing too, just in reverse (they simulate it instead).
@beardalaxy @Awoo Programs like redshift work on Xorg and can filter the colour, idk about Wayland
I also think programs like Picom allow OpenGL shaders and can be made to work per-window
I know how to program GLSL and can look into it, though idrk what a colour blindness shader does
@applejack @Awoo interesting, that seems like a pretty good bet.
tbh i have no clue what tritanopia and protanopia are like. i have deuteranopia so that is unfortunately the only frame of reference i have. i could try asking around though and try fiddling around with the other settings in windows to see if i can notice what colors they're changing. i know protanopia is similar to deuteranopia but i'm not entirely sure in which ways.
at least with deuteranopia, the way to fix it is to make greens less vibrant and make reds more vibrant. i had no idea twitch was purple until i started using the windows colorblind feature... i thought it was blue forever lol.
the way colorblind glasses from enchroma work is by filtering out green light. not completely, obviously, but it is way more toned down so it helps you see other colors without the green influence. with deuteranopia, your green cone is damaged in some way, so your red cone takes on the green cone's job and you end up seeing more green and less red due to that.
i found this randomly too lurking in a windows reddit post lol, but it seems to be pretty much the exact same idea as picom by using ogl shaders: http://wiki.compiz.org/Plugins/Colorfilter
