hey BCnSTL-
not really... but car companies do!
My vintage Amek console is gray... and I love it anyway. But he's not on TV! Don't ya think that film and video Colorists have good paying work in Hollywood for a reason?
There's a place for color choice. For me, it's mostly about legibility in the control room from a distance. And various shades of gray are not the easiest to see through for exact definition. It's cloudy, and lacks contrast. Just me- wouldn't want to force it on you for anything.
