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.
