The wash of bright colors along the Helmsley Building facade creates a festive profile for the building at night on Park Avenue. Built in 1929, the tower stands guard over the avenue. Last year, a new lighting scheme, designed by Al Borden of Philadelphia-based The Lighting Practice with LED lights was installed. Overall, more than 700 color-changing LED lights have been installed on the building, programmed into a computer than can coordinate a fanciful light show.
