Rubber Banding the Palette Graph
First, Open the Palette Properties dialog.
Select the color channel from the Color Channel tab sheet. If you do not see the tab control, click [Show >>]. NOTE: You cannot use this method if the All tab is selected.
Move the mouse pointer onto the Palette Graph.
Mouse down to grab a color curve. This makes a node, or "kink" in the line at that part of the palette curve.
Drag the node to a new location on the graph. Moving horizontally over another node erases the other node.
Release the mouse to finish moving the node.
