It would be nice if the reference channel could have the same color as the track.
I know that the color used (blue and orange) for comparison are very clear when superposing them. And then the problem could be when we use to dark color track, or to close color, etc…
But when switching track for comparison, the color track is a good indication to know what we are comparing more easily.
Having the option (activate color track for comparison) in the mixer equalizer setting would be in certain circumstances really helpful.
