Adjust background color for pdf in Preview I'm reading a lot of pdf's in Preview's full screen mode. Usually this means I'm looking at a fully white screen with black characters. I'm getting mad after an hour of reading..

Is there a way of adjusting the colours/contrast in Preview temporarily? For example in TexShop the white background is automatically changed to a grey-value. For me it's probably fine if I'd able to change the white background to grey, but maybe its possible to even change it to another color like the nightmode on iOs?

Is this possible with Preview out-of-the-box? Can it be changed temporarily/only on viewing? Thank you.
I suggest to turn on the night shift function and to push it to a warmer color map: System Preferences &gt; Displays &gt; Night Shift.


This will protect your retina and your brain.

It might be worth trying the Invert colors mode:
System Preferences &gt; Accessibility &gt; Display &gt; Invert colors.
