The function top-level-interface-dark-mode-p returns true if interface is currently displayed in dark mode and false otherwise. If interface is not displayed, top-level-interface-dark-mode-p returns false.

On Cocoa, interface is in dark mode if the name of its effective Appearance contains "dark" (ignoring case). That works for the standard appearances, but may not work for user defined ones. On GTK+ and Microsoft Windows, interface is in dark mode if its default background color is dark, which is checked summing the RGB values and comparing with 1.5.
