This is the Blurred version of my Pitch Black theme. I have changed the colors so they would look good while being transparent. There is a color scheme,Plasma theme,GTK theme, and Konsole color scheme for this theme. I use the Breeze window decorations for this theme because they are transparent. Just set you look and feel to Breeze and then set the color scheme and the Plasma theme. That is the easiest way to do it instead of changing things one at a time. This a Flat transparent theme.

I use Force blur for my Blur effect. You can find it here: https://store.kde.org/p/1294604

Also there is a complete wiki page that tells you how to get all of it working here:
