We used a vivid ultramarine in the guest room that played off of an artwork I already owned. Shells everywhere incorporated the beach into the space. A playful starfish garland is draped across the mantel, and grand seashell sconces dot the walls. The chandelier in the entry, commissioned from a company in England, is composed of hundreds of fish cast in pure white bone china. A daybed in the guest room is draped with a vintage throw, and the sofa is by Mitchell Gold + Bob Williams; the cocktail tables from Tonic Home have custom-made tops by Plexi-Craft, the side tables are by Jonathan Adler, and the walls are painted in Benjamin Moore Regal in Patriot Blue.
