There is a blog post describing this code and the reasoning behind it here: https://www.codedotshow.com/blog/coderage-2019-vcl-the-dark-side/

Free software - use for any purpose including commercial use.

function DarkModeIsEnabled: boolean; Checks the Windows registry to see if Windows Dark Mode is enabled

procedure SetAppropriateThemeMode(const DarkModeThemeName, LightModeThemeName: string);

Automatically sets a Dark Mode theme if Windows is running in Dark Mode To use:

1. Got to project properties
2. Select appearance and choose two or more themes. Note down the names!
3. In your FormCreate (or wherever) put the following line: SetAppropriateThemeMode(**name_of_the_dark_theme**, **name_of_the_non_dark_theme**);

For example:

SetAppropriateThemeMode('Carbon', 'Windows10');

procedure SetSpecificThemeMode(const AsDarkMode: Boolean; const DarkModeThemeName, LightModeThemeName: string);

Sets either a Dark Mode or non Dark mode theme based in the "AsDarkMode" boolean For example:

SetSpecificThemeMode(False, 'TheDarkModeThemeName', 'TheLightModeThemeName');

Would change the application theme to the theme with the name 'TheLightModeThemeName' if it exists.
