Menelik was designed with simplicity in mind. The theme uses contrasting shades of grey and minimal syntax colours to achieve a simple, clean visual appearance.
The creation of this theme was powered by Mike Tromba's Theme Studio for VS Code.
Personal customisations can be achieved using the workbench.colorCustomizations and the editor.tokenColorCustomizations in Visual Studio Code's user settings. More information on customisations can be found on Visual Studio Code's documentation page on theming.
