match preview background to theme color

What is the syntax for matching the pasteboard to theme color?

On the preferences pages, under interface, under Appearance, there is a check box for Matching the Pasteboard to Theme Color.

I can’t seem to get the correct information.
The only thing I can find is:


tell pasteboard preferences
		set match preview background to theme color to true
	end tell

which isn’t what I am looking for.

Also, while we are at it, what about setting the pasteboard horizontal and vertical margins?

Here is what I am up to, because I crash frequently and the preferences get hosed, I have a script that resets all my preferences:


tell application "Adobe InDesign CC 2017"
	activate
	tell document preferences
		set facing pages to false
	end tell
-- this part does not work
	tell pasteboard preferences
		set pasteboard margins to {2, 2}
		set match preview background to theme color to false
	end tell
--the above part does not work
	tell general preferences
		set use application frame to false
		set application bar shown to false
		set show legacy new document dialog to true
		set ui brightness preference to 1.0
	end tell
	tell view preferences
		set horizontal measurement units to inches
		set vertical measurement units to inches
	end tell
	tell gpu performance preferences
		set enable animated zoom to false
	end tell
	tell preflight options
		set preflight off to true
	end tell
	tell image preferences
		set preserve bounds to false
	end tell
	do script "app.applyWorkspace('SmartStream Designer');" language javascript
	
end tell

Your assistance will be greatly appreciated
