 *** SyncTeX
     Jump from a position on a page directly to the TeX source and
     vice-versa.
+*** Recolor
+    It is possible to process the colors of the page before it is
+    displayed, which is useful in certain cases (such as reading in
+    low light conditions.) This is an example that switches black and
+    white:
+#+begin_src elisp
+(add-hook 'pdf-tools-enabled-hook
+	   (lambda ()
+	     (pdf-info-setoptions :render/usecolors t
+		                  :render/foreground "white"
+		                  :render/background "black")))
+#+end_src
 *** Misc
    + Display PDF's metadata.
    + Mark a region and kill the text from the PDF.
