Which makeup shade would you choose for your walls?

There’s a book about a glamorous British duchess who insisted on having her living room painted to match her face powder. I love that she thought of this--it's very Blanche-DuBois-tutorial--in how to establish a flattering backdrop for yourself. Then, surfing the Apple site, I found is free Benjamin Moore iPhone app that lets you take a picture of anything and promptly get an exact match from their over 3,500 paint colors.

If you find a beautiful shade in your makeup bag, you can now live in it--a cheap, glamorous, and totally personal touch. Chanel eye shadow in Amethyst? Or Laura Mercier Tinted Moisturizer in Nude? My veteran decorator friend Schuyler votes for a bright watermelon pink like Tarte Cheek Stain in True Love, which she just used in a powder room for one of her Hollywood clients.

What do you think? Which cosmetic color would you turn into a paint?
