grimpicker is a color picker that uses slurp and grim. These programs rely on zwlr_layer_shell_v1 and wlr-screencopy-unstable-v1 (maybe be replaced with ext-image-capture-source-v1 and ext-image-copy-capture-v1 in the future) wayland protocols (implemented in wlroots-based compositors, e.g. sway).
It has several output options, they can be combined.
--copy needs wl-clipboard to be installed.
--draw and --escape need a terminal with truecolor support (e.g. foot).
--notify needs libnotify to be installed and a notification daemon (e.g. mako or fnott) to be running.
--print and --draw are selected by default if no arguments are provided.
An example usage pattern is to add this binding to your sway config:
# Super+Print: color picker
bindsym --to-code $mod+Print exec grimpicker --notify
