The dealership told me that my interior color, code #275 is "Cream beige", but this website

tells me that #275 is Mushroom. So I guess they're the same thing. On eBay many people have advertised their cars as having "Parchment" interiors but when I decode the VIN's it comes up as either mushroom or cream. My question is, does cream beige = mushroom = cream = parchment?

I'm looking to replace some interior items, so it's pretty important for me get this straight.
