Zitong Hui expands Central Park research on urban darkness

Landscape designer Zitong Hui is extending her graduate thesis, Darkness Matters, into an ongoing research project on how artificial light shapes nighttime experience in Central Park, New York. The work links visualization, ecology and landscape architecture to show why darkness itself matters in dense cities.

Why it matters: - Urban light pollution is changing how cities look, feel and function after sunset. - Zitong Hui’s project argues that darkness is a spatial condition, not just the absence of light. - The research suggests landscape architecture can shape nighttime experience as actively as it shapes daytime space. - The work also raises ecological questions about how artificial illumination affects birds, insects, bats and small mammals in Central Park.

What happened: - Landscape designer Zitong Hui, also known as Shirley, developed “Darkness Matters” as a graduate thesis project at the Rhode Island School of Design. - Hui has continued the project as an ongoing design research initiative focused on Central Park in New York. - The project examines artificial light, ecological conditions and nighttime spatial experience in the park. - Hui shared the project alongside an Instagram profile, Shirley’s Palette.

The details: - Central Park sits inside one of the world’s most intensely illuminated urban environments. - The park creates a contrast between Manhattan’s brightness and the relative darkness of landscape. - Along the park’s edges, illuminated buildings and streets remain highly visible. - Farther inside the park, vegetation, topography, water and distance interrupt the city glow. - Hui uses mapping, photography, spatial observation, digital modeling, environmental data and visual analysis to study how artificial light interacts with landscape conditions. - The project translates these conditions into drawings, maps, diagrams and spatial sequences. - Pathways, tree canopies, open lawns, water bodies, elevation changes and skyline views all shape how nighttime environments are perceived. - The research treats darkness as a gradient rather than a binary condition. - Moving from Manhattan into Central Park can shift from bright streets and park entrances to partially shaded paths and enclosed landscapes where the city fades from view. - The project identifies several design strategies for shaping darkness. - Berms, depressions and other topographic changes can block or redirect surrounding light. - Layered vegetation and tree canopies can create different degrees of enclosure. - Visual framing can reveal or conceal illuminated buildings, landscape features and the night sky. - Lighting design can also change atmosphere through brightness, color temperature, direction, spacing and duration. - In this approach, light and darkness function as complementary elements rather than opposites.

Between the lines: - The project moves the conversation about light pollution beyond technical mitigation. - Hui is reframing darkness as something that can be designed, protected and experienced. - Visualization is doing double duty here as both research method and design tool. - That approach makes an often-overlooked part of the urban environment easier to read and discuss. - The ecological framing also broadens the project beyond human perception alone.

What's next: - Hui’s work will continue as an ongoing investigation of Central Park’s nighttime conditions. - The project will keep testing how landscape architecture can make urban darkness visible again. - Future design questions center on how cities can balance illumination, ecology and human experience after sunset.

The bottom line: - Darkness Matters argues that urban darkness is not leftover space. It is a designed condition that can shape ecology, atmosphere and the way people experience the city at night.
