I agree with Greg that Brown & ivory were “it” back in the day. Red and IG Orange were commercial items, the red for emergency circuits in healthcare, the orange were isolated ground,
The color palette of decorator inspired choices started up in the late 70s, and expanded from there. Now, there are high end decorator configurations, naturally in decorator finishes. Faceplates with no visible screws, etc.
And yes, I also have been around for quite some time.
