Hi,
I'm colour blind (deutan), and I'm looking for a screen filter that can help me better distinguish colours. I'm using Arch with xfce4. I did a quick search on Google, but I was unable to find anything functional. Do you know of any filter I can use? I'm sorry if I'm posting on the wrong forum.

Not sure if it's exactly what you want, but if you go into your settings manager and click on Appearance you can change the global theme.
You can google "xfce themes" or figure out how to make your own if one of the defaults doesn't work.
If changing the color temperature will help you could try messing with redshift.

For my vision issues I have found that xgamma helps....
If you install xgamma and play with the settings you may get something that works. Here's what I use:
xgamma -gamma 0.80 &

No idea whether that can help you, but
xrandr --output HDMI-whatever_lookatxrandr-q --gamma 1:0.01:1 # tints the screen magenta, green will get dark
xrandr --output HDMI-whatever_lookatxrandr-q --gamma 0.01:1:1 # tints the screen cyan, red will get dark
xrandr --output HDMI-whatever_lookatxrandr-q --gamma 1:1:1 # back to normal

Apparently, no decisive solution exists, but these are interesting workarounds. I'm marking the thread as solved, thanks to all who replied.

I have another idea. You can probably replace the xfce composition manger with picom. (i.e. disable it in xfce and autostart picom)
picom supports custom glsl shaders (setting glx-fshader-win), so you could write your own color shifting shader, maybe based on http://blog.noblemaster.com/2013/10/26/ … nt-page-1/

Do you have an nvidia GPU?
I just tried "nvidia-settings -a DigitalVibrance=1023" on a deutan simulation image and it ended up more like the original, but since the defect is in your vision and not the image, idk. whether that'll work.
