Prism is for Nix/NixOS. It's a simple home-manager module the allows you add a directory of wallpapers, and recolor them. It has most colorschemes, allows you to use nix-colors, or make your own in the base16 format.
Thanks I'll check it out, sorry for taking a long time to respond btw. I forgot my login details lol
Yes, all it does is generate wallpapers and place them in your home folder. Defaults to
~/.config/wallpapers
