What Is a Color Space and Why Is It So Important?
Every scanner, digital camera, software program, monitor, and printer — every device or program that you use to create, manipulate, or output images — renders color in a different way. Each device works within its own color space, the portion of the color spectrum that it can reproduce.For instance, a computer monitor uses red, green, and blue light to create color; a color inkjet printer uses cyan, yellow, magenta, and black inks to create color; and a digital camera records the color it sees using daylight (which has a yellowish cast) or a flash (which has a bluish cast). How can any of these devices ever manage to create some kind of color match without some help? They can’t. That’s where color management goes to work.
