What color interior is this?

I have a 72 Dodge Demon with a "GY4" interior paint code on my fender tag, however the seats, headliner, panels, etc... are a different color than the dash is.

I believe that the dash color is indeed GY4 (gold), but since the seats and door panels are clearly a different color. How would I find out what the correct Mopar name/color code for it is?

The rear package tray on this car did not come with the perforations for rear speakers and since I want to install some speakers in that location; I want to order a new package tray with holes...just have to make sure I'm ordering the right color!

Are all "GY4" interiors this way?
