Color and black and white use different design elements and principles in entirely different ways. Some elements, like line, shape,size,texture,and value are important in B&W. Hue, or color, is absent.
Without color, many natural and man-made objects appear less-interesting and more "similar"...subtle patterns that are done in color on say, clothing, tend to "disappear" when captured in B&W. Recently, a beginner shot a photo of a bed of seashells; in color, she felt that it looked like "chaos"...that was one of her title words, chaos. Had the photo been made in B&W, in the fairly flat,open shade in which it had been shot, the shadows would have been dull and lifeless, and the entire feeling and effect of "difference" and "chaos" would have subsided--dramatically!!!
The BEST lighting for color photography is often not the BEST lighting for B&W photography. A really good example is in portraiture: for color work, pure white umbrellas look pretty good. For optimal rendering in B&W, slightly smaller umbrellas look better, as do umbrellas with silvered interior fabrics....they produce a "crisper" light that tends to look better in B&W images.
In B&W, oftentimes the shapes and lines of the subject take on a critical importance, and if the shapes and lines are not very strong, a B&W photo of a certain scene or subject might not appear of much interest; if however, color is added, then the subject or scene might appear quite interesting. In B&W, contrast between elements is not easily shown when the color differences are slight; in color photography, slight color differences can often be quite visible. Sometimes REMOVING all of the color can improve a photo, by eliminating distracting colors or discordant colors. SOmetimes ditching B&W and going to a full-color rendition is the only ay to make a scene or subject come alive.
