Actually this helped me quite a bit.  I didn't realize the theme needed to be set to 'Mercury' before you could change the track colors like this.  Unknowingly I had mine set to the 'Tungsten.' So why can they be changed in 'Mercury,' but not in 'Tungsten?'  Or perhaps I am just missing something.  

Track color changes were introduced in X3. Unfortunately, the theme feature is not compatible with the track color feature. Mercury is not a theme in the same sense as Tungten. Mercury is the original resource file used by SONAR. Tungsten and all the user created themes are modifications to Mercury.

^^^
 
AND... all custom themes (Tungsten & 3rd party) are stored and accessed outside of Sonar's operational files so it can't manipulate them in the same manner it does Mercury.
 
It's also possible (tho highly speculative on my part) that custom themes overlap the Mercury theme, covering it up, making it more difficult for Sonar to manipulate them.
 
Even so, it has been mentioned in the past that colorization of custom theme tracks may be possible in the future.

Good to know about Mercury and tungsten.
thanks
