Answer 1

Here is the ghostscript solution for Windows, which requires grep from GnuWin (http://gnuwin32.sourceforge.net/packages/grep.htm):

Monochrome (Black and White) pages:

gswin64c -q -o - -sDEVICE=inkcov DOCUMENT.pdf | grep "^ 0.00000 0.00000 0.00000" | find /c /v ""

Color pages:

gswin64c -q -o - -sDEVICE=inkcov DOCUMENT.pdf | grep -v "^ 0.00000 0.00000 0.00000" | find /c /v ""

Total pages (you get this one easier from any pdf reader):

gswin64c -q -o - -sDEVICE=inkcov DOCUMENT.pdf | find /c /v ""
