We've all seen the black and white version of this photograph by Alfred Eisenstaedt. It was taken on V-J Day in Times Square and was published in Life magazine in 1945.
Reddit user mygrapefruit colorized the photo using Photoshop CS 5 on a Wacom tablet. "I found some vintage postcards of Times Square to figure out the color of the buildings and some signs," she said. "The rest of the colors I guessed by using common sense."
