How change the colour of the pasteboard in cs6?

Hi, since you posted in the InDesign Scripting forum:

Don't know, if you really want to change the Preview Background, because this is not the color of the pasteboard when the screenMode of a layoutWindow is set to PREVIEW_OFF (your screenshot is suggesting this). The color of the pasteboard cannot be changed when in that mode. At least not that I know…

But if you really were looking for a different Preview Background color, check for previewBackgroundColor of the pasteboardPreferences.

See for example Jongware's ExtendScript DOM documentation for InDesign CS6:

Adobe InDesign CS6 (8.0) Object Model JS: PasteboardPreference

It is available in the preference.. press cmd+k shortcut for mac.. change the Preview Background color as you wish
