Question about colors-waybar.css

[Genolka]

Hi, I don't understand where and how generating ../../.cache/wal/colors-waybar.css file.
Its used in a lot of css files.
Is it generated by some script based on wallpaper? Cause I looked in .config/wal directory, but not sure if it is what I'm looking for.
(I'm using not Arch, but NixOS, that why I manually choose some parts from your rice, your rice are incredible)

Do you have the hyperland.config line for the wallpaper selection? bind= ALT, w, exec, ~/.config/hypr/wallpaper.sh. When you press those you will be able to select the wallpaper from the folder (for me the folder is in home/wallpapers/walls). After selecting it, it will create the colors out of the ones in your wallpaper.
It took me long to figure how to make it, hopefully this is helpful for you!
