When it comes to ancient Egypt, the color most associated with its monuments today would likely be a sandy beige. Egyptologists, however, have long known that many of its buildings were actually covered in vividly colored paintings that brought the stone structures to life. Now, through the magic of projection-mapping technology, visitors to the Metropolitan Museum of Art can catch a glimpse of what one of these buildings, the Temple of Dendur, may have looked like more than 2,000 years ago.
