# A script to easily pick a color on a wayland session by using:
|
|
# slurp to select the location, grim to get the pixel, convert
|
|
# to make the pixel a hex number and zenity to display a nice color
|
|
# selector dialog where the picked color can be tweaked further.
|
|
#
|
|
# The script was possible thanks to the useful information on:
|
|
# https://www.trst.co/simple-colour-picker-in-sway-wayland.html
|
|
# https://unix.stackexchange.com/questions/320070/is-there-a-colour-picker-that-works-with-wayland-or-xwayland/523805#523805
