But Ms. Guinness does not acknowledge that at these dinners, she is both inherited wealth (the banking side of the Guinness brand) as well as divorced wealth (hello Spyros Niarchos). The combination of both allows her to purchase, say, Isabella Blow's entire and considerable closet.
However, if Ms. Guinness would like to treat me to dinner, I'd be delighted to hold forth with her on color. Here is a short book list for her to read in preparation:
Victoria Findlay's Color: A Natural History of the Palette
Simon Garfield's Mauve: How One Man Invented a Color that Changed the World
Michel Pastoureau's Blue: The History of a Color
another by Pastoureau, not only on color: The Devil's Cloth: A History of Stripes
I am confident that we would have plenty to talk about, from the appetizer through the amuse bouche, through a third pint of Guinness (my favorite beer, actually) and onward to dessert, with nary a twinge in our digestive systems.
