As you indicate, those colors do not depend on the theme, but on the user.
Recently Rui added a feature so that the background color was automatically selected in a light version of the foreground.
You simply select the foreground and press "auto" in the background.
Qtractor has a functionality that allows you to control the saturation of the colors in the list. I consider that it should be accessible from that same form, however, since it is a general configuration, we find it in:
view > options > display > track color saturation
For technical purposes it is a general configuration, but for practical purposes it is a track configuration. Where it is goes unnoticed.
