Zorin OS is a Linux desktop that is developed in Ireland. So what's more natural than to create a theme that takes up an Irish motif: Mt Slievemore on Achill Island with its beautiful Silver Strand. This theme is not affiliated with Zorin Ltd but made by me, only mimicking the colours of the desktop's dark theme.

You want it darker
I don't use Zorin OS - although I did in the past - but that's a nice theme on any kind of OS.
