Instead of changing a track colour one by one you can do it in groups. The old 1960's + analogue organs had a color code for instrument groups, so green for piano/guitar, white for flutes etc, so if you use a similar group coloring method you can select multiple tracks holding CTRL and make a selection, that selection will apply to all the selected tracks at once. Tracks 1,2 then 3,4,5 were colored together, 2 choices instead of 5. The tracks don't have to be together, you can change tracks 1,4,7,10 in one go. (for instance).
