I was hoping to be able to fix
this issue by using the Theme Editor, and also change the colors of the buttons in the FX Racks. But, as the OP says, changing even a single color using the editor and saving the theme removes the full strip coloring capability from the Mercury theme (which is my favorite theme among all DAWs).

I've been asking for nearly a decade and ProTools had this figured out many many versions ago. I've been a Cakewalk user for 18 years, since Pro Audio 8. I'm loyal. But this has frustrated me for so long that I'm downloading ProTools First just to see if I like it. Hopefully I won't. 
Any reason why you don't use Panu's Duckbar? Maybe it doesn't work in post-X3 SONAR versions? I've never used it, so I don't know. If it still works, I think it's better than switching to Pro Tools and learning everything from scratch. Btw, your claims are fully understandable. I don't find the thread negative at all.

Thought I would keep it real simple, edit just one colour in this new Theme Editor. I was able to change the Track Text Name colour in Track View for all "Instrument Tracks". YAY ! However, when I change the Track Text Name colour in Console View to that same colour . . . it just doesn't work ? I've gone over it a number of times, but just can't get it to work.
I'm not sure because I don't use Simple Instrument Tracks, but can't the track text name color for SITs be changed via the Preferences' Colors page? Or maybe the issue I pointed to above also broke it??
