Think about how many times you've flipped through a magazine and seen it: a black-and-white image spread across the page, with a bold splash of color highlighting part of the scene. Maybe it's the blue eyes of a model, or the bright plumage of a bird as it wings across the page, but that simple break from the monochrome background draws your eye and captures your attention.
