Channel vs Master Fader Metering Appearance

Hello all.
I’m trying to configure my colours for my faders. Preferences=>Metering=>Appearance
When i adjust the colors in channel faders the same colors apply to my stereo out. Everything i adjust in master fader is not applied to my stereo out. Why?
Any help appreciated thanks!

Ok i just found out that the master fader is in control room not the main stereo out in the mixer.
It would be nice if we could change the stereo out colour sheme.
