Good – that would be a workable hack if the text also inverted, but it seems to leave me with black on black invisible text. So each time I print I presumably have to manually change both background colors and print colors ?

What would you recommend (in the absence of workflows/scripts) as a quick way of switching between a dark and light scheme ?

(In Editorial, for example, a single switch inverts the display scheme, without changing the printing properties of the document).
