16,581,375 is a video art piece programmed using P5.js. The colors are changing constantly, slightly, but randomly generated by the computer. Therefore, at any given time the colors are different from the frame before; at the same time, every time the program runs from the start and the video starts playing, the colors are also different from any other times. The number 16,581,375 is the result of the maximum red value (255) times the maximum of green value (255) times the maximum of blue value (255).
