Is there a way to randomize the colour of existing tracks?

Just wondering if there’s a way of applying a random colour to a selection of existing tracks. I’m aware that you can have Cubase pick a random colour for new tracks when they are created but couldn’t find a way to do this with existing tracks.

Perhaps I’m missing something or maybe there’s a way of doing this with the Project Logical Editor?

The PLE would be where you’d do this. However the Set Color parameter can only be set to a fixed value. So no.
