Colors mail app with mixture of dark and light colors. Kind of a joke calling it a customizer since so far there are no options to configure, but if you like how it looks feel free to install. IOS 11.x only...Don’t worry options will be added for every colored feature. This is infant of a beta tweak.
Added on/off switch and laid groundwork to start adding more preferences/ settings.
