Photoshop's Replace Color command lets you create a selection, based on image color, and replace that color selection with any other color. The Replace Color adjustment accomplishes this by giving you access to the three items that control color: Hue, Saturation, and Brightness. Hue gives you the ability to change the images physical color, Saturation controls the amount of color, and Brightness determines how bright the color is, based on its Hue and Saturation.
