The Arc theme of Horst3180 is a beautiful theme but it only comes in one colour. That is why I went looking for the possibility to change the colours. First I tried it manually. And what can be done manually, can be automated later. That is the power of linux. These Arc Colora scripts work on more than one distro.
We follow the scripts from this github and install some specific Solus applications to be able to install the new Arc theme.
Install the following applications by copy/pasting this line and you will be just fine.
sudo eopkg it -y gcolor3 optipng autoconf automake pkg-config libgtk-3-devel m4 make
or run the script
The result of this tutorial (and many more) can be downloaded from the github at https://github.com/erikdubois/Ultimate-Solus.
Arc Orange came into existence.
