Hello,
macOS Mojave has introduced the Dark mode. Is it possible to read if my application is run with macOS set to Dark mode? I need to have a yes/no variable in order to perform adjustments (setting colours).

If the answer is "Dark," it's dark -- if anything else, such as "The
domain/default pair of (kCFPreferencesAnyApplication,
AppleInterfaceStyle) does not exist", it's light.
A version of Tk is currently in development that will provide automatic
support/theme switching for dark mode in the ttk widgets, and
near-complete support in Tk widgets.

This only reads the setting in System Preferences, and may not reflect

any per-app setting or override. I think what is being asked is how to
tell if a specific running program is using dark mode (Welle informed me
that this can depend on whether Tk is run from a script versus in an app
bundle).
One question I have on this topic: do/should <<LightAqua>> or
<<DarkAqua>> occur when a program is first launched?

Hi all,
Thank you Kevin for your answer. This has helped me a lot.
Christopher, your point is interesting, I did not thought about overridings and so on. For the moment, however, Kevin solution seems to work fine, at least in standard scenarios. Since it gets the current state Dark/Light from the System Preferences, I think it is fair enough to assume that this setting will be applied to the application.

I just noticed Marc Culler's solution added to core-8-6-branch a couple months ago, which is described in macosx/README, and mentioned on the Wiki: https://wiki.tcl-lang.org/page/Tk+differences+on+Mac+OS+X "

To get the current appearance of a window as a boolean value:
tk::unsupported::MacWindowStyle isdark window
To get/set the appearance as "aqua"/"darkaqua"/"auto":
tk::unsupported::MacWindowStyle appearance window ?newAppearance?
