Our eyes are attracted to color, and enhancing the color of an image or part of an image can insinuate the time of day, enhance emotional impact, create an intriguing mood, and add cohesiveness in an image. Juxtaposing cooler and warmer colors often adds a pleasing visual tension, which also attracts the eye.
Color is made up of three attributes—hue (the color), saturation (how much color), and brightness (how dark or light the color is), as illustrated in figure 12.90. Keep these three components in mind when making decisions to enhance and fine-tune your images. Often how much color or how bright the color is can be just as important as what color you are using.
