This is a script I wrote to make my terminal-covered monitors look a bit more colourful. A random dark background colour is selected and added into a temporary configuration file for Sakura.
I've also put the colour into the environment so that zsh running on a 256-colour terminal can use it in a matching prompt.
Colour Sakura Script: ColourSakura.sh
Example matching zshrc: ColourSakura.zshrc
