Adjust Color

HSB: Presents a dialog that enables the adjustment of the hue, saturation, and brighness component of the colors in an image. The Upper Threshold and Lower Threshold controls can be used to limit the modification to only those colors whose saturation and brightness fall between the two (these threshold values do not work with the Hue component).

Contrast/Brightness: Presents a dialog allowing the modification of the contrast and brightness levels in an image. The Upper Threshold and Lower Threshold controls can be used to limit the modification to only those colors whose contrast and brightness falle between the two values.
