Using the Hue/ Saturation and Desaturate Commands

The Hue/Saturation adjustment gives you separate control over an image's Hue, Saturation, and Brightness, and it's Colorize option lets you apply a color cast to an image that's similar to a duotone effect. The Desaturate command removes all the color from an image, which preserves the Hue and Brightness values of the pixels, and changes the Saturation value to zero. The result is a grayscale image.
