N6.0.4 seems to provide more colour changing possibilities, which is good, but it still does not appear possible to change the general black background of the MixConsole.

I don’t understand why the MixConsole base colour seems to be hard-written as black when many other parts of the system can now be customized.

Am I missing something?

I just got my N6 update and this is exactly my main criticism. All seems to work smooth here on my MacPro but the dark mixer is mostly harder to decipher than before. I can cope with the new functions but I need the mixer desperately in lighter colors for easiness on the eyes. And while you are at it: please get rid of the silly and amateurish looking metal brush look for the empty space there.

100% agreed !
