git clone https://github.com/Kuari/Xfce4-terminal-colors-for-transparent.git
cp Xfce4-terminal-colors-for-transparent/For_transparent.theme /usr/share/xfce4/terminal/colorschemes
Then, select For_transparent in the xfce4-terminal setting.
When I tried a lot of excellent color schemes, but I didn't like them very much. I decided to write my own configuration, only for the transparent xfce4-terminal.
