This quick tutorial shows how to install ‘Yaru-Colors’, default Yaru theme in different colors in Ubuntu 19.04.

To install the theme:
1. First grab the source tarball from the them project page:

Answer some questions (type number 1, 2, 3, etc.) to select which to install, theme folder (leave blank and hit Enter for default).
4. Once installed, launch Gnome Tweaks (install it via Ubuntu Software) and navigate to Appearance.
There change the values of applications and icons to apply new themes as you want.
