This may (or may not) help. I just did a very quick test... what you might try is selecting a theme that presents the Dax logo the way that you prefer then modify those colors. In my test, the logo remained the same even after I altered the header color. I'm sure that it's not everything that you're looking for but it might be a step in the right direction.
