Color Adjustment allows the adjustment of Brightness, Contrast, and Saturation of the selected item via individual sliders.
Brightness - Adjusts the overall brightness of the image. This offsets the RGB components by some amount; in other words, a fixed value (determined by the slider position) is added to all three color components for each pixel. Values greater than 0 approach white, and less than 0 approach black.
Contrast - Adjusts the overall contrast of the image by moving the bright and dark components further apart (for settings greater than zero) or closer together (for settings less than zero).
Saturation - Adjusts the intensity of the color without affecting the luminance. Values greater than 0 cause colors to become more intense, and values less than 0 approach grayscale.
