Big advertisements probably have a lot more color than the normal red-yellow-white you see from traffic. Chances are it's not quite so vivid to the naked eye, but a camera sensor with nice flat full-spectrum sensitivity can reveal all the color. You see this a lot with telescope photos; in low light our eyes mostly just pick everything in the sky as white dots, but a photograph can capture a lot more.
