Color multiple tracks at once

I’ve got 8 guitar tracks all in the default army green color. How do I change the color to red on all 8 tracks at once? These all happen to be audio and mono though I don’t think that makes any difference. Thanks!

Select them all by using the ctrl-button and clicking on them one by one or, if the tracks are adjacent, by selecting the first one, pressing shift and selecting the last one and the use the colour dropdown to assign the desired colour.
