It was originally orange-red colored and belongs to the ChromeOS KDE Light by Adolfo KDE global theme, but I’m a blue kind of guy so I changed the hue. The one on th left is covered with whatever I’m doing, it’s the large external monitor. On the right is the built-in laptop monitor where I need the large triangular shape for my conky’s.
That monitor has a bit more pixels than the external one, hence the black rectangle in the top left.
GNOME extension changes my wallpaper every 5 minutes, I have over 700 saved allready. Sometimes, maybe once in a month it gets stuck somehow. This is my wallapaper until next restart…
