How can I easily color-code voices?

I have two voices on a single staff. I am trying to color-code one of the voices in a pale color, so that the other voice stands out.

I don't seem to be able to select a range of notes of only one voice (shift-click). Both voices are selected.

If I select individual notes, only the note-heads are selected. I seem to have to select one part of one note at a time, and change the color of the note-head, the dot (for dotted notes), the stem, and the beam, separately.

It is a laborious process, and I would be grateful if you could suggest an easier way for me to do this.

(I am using MuseScore 2.1 under Windows 10).
