Changing note colour

I need to change the colour from black to red of all the note heads, stems, tails, accidentals and rests over 16 bars.
I can do this using the Inspector but only each item one-at-a-time in every bar - a very long and tedious task.
Is there an easier and less time-consuming way to achieve the colour change of all the contents of the 16 bars?
Help will be much appreciated -
