Should my obs audio be in green, yellow, or red?

Speech should be firmly in the yellow zone on the meter, sometimes touching the red zone.

Nothing should live fully in the red, that is audio clipping and a bad time for everyone.

Other stuff like background music, game sounds/music, ambient noise should live somewhere in the green (if you even intend to have it at all) and shouldn't even peak into the yellow, let alone the red.
