I just found out that Morticia was quite the colorful decorator!
This is a picture of the actual color scheme that the Addam's house was on the set of The Addams Family. It was just a jumble of odds and ends from various other defunct TV sets. To keep the vision of the original drawings, they shot it in black and white.
Also, I just learned that the Addams family had a motto AND that I know know what I want on my tombstone: Sic gorgiamus allos subjectatos nunc. Meaning, "We feast on those who would subdue us." You can read the whole story here.
Thank you, Thing.
