This desktop tuning just started with a wallpaper. I changed the colour of the conky to pink and then wondered how it would look if I go all the way to change it to pink.
This wallpaper is the culprit.
All information how to do this yourself can be found on this website.
Arc Theme Colora, Sardi Flexible, Conky Aureola can be found in the menu.
And it resulted in this.
This review I made of Ubuntu 16.10 might also explain more about the theming.
