It’s not your imagination. The Exo apartment building at 1897 Oracle Way in Reston really does change colors.

Designed by R2L Architects and developed by Greystar, Exo is constructed with color-shifting metal panels that change the building’s facade from dark royal blue to blue-green depending on the angle of the sun. Renters can select their own colors inside, choosing among warm, cool, relaxing and uplifting paints.

The 16-story Exo includes 457 apartments in two towers, all with smart-home features such as “View Dynamic Glass” windows that can be controlled by an app to allow in natural light while reducing glare and energy costs and eliminating the need for shades or curtains. The apartments also have keyless entry, a Nest smart thermostat, energy-efficient appliances, wood floors, quartz counters and a washer and dryer.

The one-, two- and three-bedroom apartments, which rent from $2,105 to $6,120 per month, range from 700 to 1,413 square feet. The upper two floors of both towers include upgraded penthouses with floor-to-ceiling windows and private terraces.

Building amenities include a saltwater swimming pool surrounded by cabanas and grilling areas, two penthouse lounges, a fitness facility, a yoga studio, a meditation lawn, bike storage, a pet spa and a 24-hour front desk with concierge services.
