Tint Rows with Label Color not working...

I have a project containing several dozen documents, each labeled with one of eight or nine labels I’ve defined. In outline view, going to View > Outliner > Tint Rows with Label Color does nothing. I just see text on a white background. The “Label” column displays a small square with the color, of course, but that’s it. I’ve tried this with several different projects with the same result. Am I missing something? I’d love to make use of the visual color cue.

Make sure you have the tint opacity setting set to High.

First, thanks for the breathtakingly swift response! Second, yes indeed, I was missing something: changing that preference setting did the trick. How I could have pored through the prefs without seeing it, I don’t know: I must have stopped at the word “Pin,” thinking it was not what I was looking for. Cheers!
