Hello, Blue Note! I'm glad you enjoyed it. :) Shortcuts can vary slightly depending on the version, so if you want to check the exact version of the shortcut that I'm using, you can check it out by going to Key Commands in the top Logic Pro X menu!
Also, if you press Option+C to set the color palette, you can set it to the color you want. In my case, I set the option to automatically specify a different color for the top menu Logic Pro X - Preferences - General - Display - Track - Auto Progress 24 in the Auto Progress menu. I set it to 96:)
