+***** NOTES/COMMENTS
+
+background:
+portrait was provided for print/paper copy and is great for that in monochrome
+(without grays for colored links),
+landscape better matching a screen for visual presentations, color affecting the landscape only
+
+solution:
+make configurable by cli & rc file
+make both (portrait & landscape colors) configurable
+either as hyperlinks monochrome or colored
+overriding existing default which remains as described
+
+document
+cli:
+--pdf-hyperlinks-no-color or --pdf-hyperlinks-mono
+--pdf-hyperlinks-color
