Input/output Chroma input and output levels for the point levels under the cursor in the edit display.

Restores the chroma curve to linear. Control-click (Windows) or command-click (Macintosh) to restore the curves for luminosity, chroma, and hue to linear. The Hue Editor When Hue is selected from the menu at the top of the LCH Editor palette, the editor takes on the appearance shown on the following page. The controls for editing hue are unique, consisting of a rainbow-colored background bisected by a straight line, representing the hues (colors) in the original image. Superimposed on this line is another representing the colors in the image after editing. Before editing, the output line is the same as the input line, so that, for example, reds in the input will be represented as red in the final image. By changing the shape of this line, you can change the relationship between input and output colors over a portion of the color range, with the result that colors that are red in the original might be output as orange, or even green or blue.
