The lobby of the new Hotel Palomar Chicago, designed by Orlando Diaz-Azcuy, offers an easy formula for how to inject a space with a sense of lightness and fun: Just add white. Those little white stools with stacks of books, along with the white chandelier, lamps, urns, and sheer white window treatments are so refreshing contrasting the more practical darker fabrics on the sofa and chairs. What a great way to forgo light-colored upholstery but still get an airy, sunny effect.
