Shemitz is, perhaps, most famous for his work with the Grand Central Terminal in Manhattan. He used "blue filtered tints" and magenta colored lighting to accent the exterior façade architectural elements of Grand Central. He explained his reasoning for his choice of colors in a 1991 interview with "The New York Times", "I think the most important issue is to make New York a lively, friendly and joyful place." He is also well known for his work on the Thomas Jefferson Memorial in Washington, D.C.
