Inside, Stayner nodded to the Mesoamerican colors, textures, and forms found in mid 20^th-century works by Luis Barragán and Juan O’Gorman. A brick wall features a bold mural; the wood ceiling and joists are painted bright yellow; furniture, floors, and walls are made of ash wood, treated with tongue oil or blackened. With a similar sense of craft, the firm developed a cementitious terrazzo for the table- and bar tops. For electric illumination, says Stayner, “We wanted lights that, during the day, were compatible with the natural light, not overly yellow and orange. At the same time, we didn’t want the light at night to be so blue it would be unpleasant.”

To capture the range of color temperatures and output flexibility necessary to mimic nature’s spectrum—a span from 1,400 to 10,000 Kelvin—Stayner chose a series of tunable RGBW LED lamps that offer more hue variations than tunable-white options. These are controlled by a wireless system (from the same manufacturer to avoid potential protocol conflicts) that responds to an astronomical clock. This maintains a light consistent with the sun streaming in from the street and skylights throughout the day, all year. In the evening, the lights dim to a warm glow for a more intimate ambience. At the same time, strategically placed lamps are tuned to amplify colorful design accents within the space and complement the food. All the lamps are individually addressable for on-the-fly adjustments via wall keypads or an app on the owners’ phones. “We can also remotely push new programming to their lighting,” says Stayner.

While the number of variables and controls at Tamarindo may seem intimidating, he notes that the wireless, individually addressable system also presented surprising opportunities after installation. “For us as architects, not lighting designers, this really opens up possibilities,” Stayner adds. “It’s great to have this level of control, especially for a hospitality setting.”
