Adjust Red, Green, and Blue (RGB)

The RGB dialog box adjusts the red, green and blue color values for every pixel in the image.  

A value of 0 is the normal image value of a pixel for each of the RGB components. The value represents the increase or decrease in percentage of a color for each pixel.  A value of -100 means the image has none of that color in it.  If all values are -100 the image is black.  A value of 100 doubles the intensity of a color.

  1. Do one of the following:

  2. In the dialog box, adjust the Red, Green and Blue options.

  3. Click the Proof button to view a preview in the Main Display area.  Change the setting as you like.
