I seem to only have colored numbers. My topbar is still orange.
You've probably hit the karma threshold where you can set the top bar to any color, and have the default color set (if you go to your profile page there would be a "topcolor" field)
Looks like you have the best of both worlds. :)

(Though as I was posting this, I briefly got all Marooned, then it went back to standard orange.)
I'm seeing maroon when I make a comment/reply (e.g. now), but othewise orange.
The reply page does not use your topcolor, so it will always be the default.
