As the show is in black and white, one might still recognice Morticia is wearing a more pale red, perhaps a tiny bit towards the orange, because this was the fashion at the time. I believe so since the lips are not that dark. You might also see the same in her nails.
I myself prefer a more red going towards cerise. For this style I recommend the same color as Elizabeth Arden's Cranberry Cream 02.
I do NOT recommend Elizabeth Arden itself - it's overprized and make my lips dry. But this color is perfect for my skintone. Buy a cheap and good one instead. I bought mine on sale - otherwise I'd nerver would have bought it.
As lipliner I recommend Maybelline 54 Bordeaux. This is a perfect liner to the color in the Arden lipstick. Cheap too.
