Universal Fader Wing LEDs

Probably inhibits and grandmasters

I don't know this for certain, but on Nomad, if you assign a Palette the Fader turns Brown.
idk if that happens on the Fader Wing too. Never did it in real life.

Nope, I very much doubt that any LED can produce brown to start with, but I'm not sure what colour the fader buttons glow when a palette, preset or anything other than a cue list or submaster is assigned to a handle on the Eos or Gio. As far as I know, those consoles only have red, green and white LEDs (oddly not blue) in their macro buttons. I'm not sure if this is also the case with the fader go buttons. Come to think of it, I'm not actually sure if the buttons on the universal fader wing can be lit anything other than green. Even if an inhibitive sub is loaded to one, perhaps it still glows green, despite appearing red on the fader ribbon within Eos. Could someone from ETC perhaps give a definitive answer about this?

You took my comment a little too literally there, but I understand.
I'm spoiled for having the new EOS Fader Wing on my Xe20, so I'm not positive about the Universal Fader Wing dynamics.
but the EOS Fader Wing only does Green or Red.

The universal fader wing only does red and green
