Make Skype's tray icon monochrome on Linux

Before/after:

TL;DR: Use skype1ico

This was done on Arch Linux and KDE Plasma 5, but other systems will work

wzxhzdk:0

Remember the path to this skype1ico folder.

Make this shell script which you will start Skype with:

wzxhzdk:1

And here's the theme itself (paste this into the file):

wzxhzdk:2

This theme just uses the environment's native icons, which are hopefully monochrome or better fitting.

The supplied picture-based themes don't seem to work with KDE Plasma...
