They don’t show up against a light background, which I much prefer to work on over a dark one - it’s much better for my bad eyes and feels more “pro” for me. Is there a way to make the automation lanes darker? I don’t think so, but I’m hoping I’m wrong.
I think the automation line follows the track colour. So if you change the automation lane track colour the line should change as well.
Automation follows the track colour BUT, if you select the automation lane and use the colour menu from the top bar (not the inspector), you can independently colour it.
