Please correct me if I'm wrong but isn't the grey panel behind the faders called the "Console View Strip Background" ?
I'm trying to get away from the dull grey and have attempted to change it, saving my own color scheme ( SK_1 ) multiple times and it doesn't work.
I just used pink to make it really obvious if something else was being effected by that color change ... but nope.
There is nothing pink in the whole console view after making the change.
Some of them work and some of them don't. I have restarted X2 mutliple times. Deleted and recreated my color change on the stip background multiple times also but still no change.
