Hue/Saturation

The Hue/Saturation command in the Adjust section of the Image menu allows you to edit colors using the Hue Saturation Brightness (HSB) model.

Basically, you can take either all the image colors together or select a single color, then change the hue, saturation or brightness accordingly.

In the "Hue/Saturation" dialog there are sliders for the hue, saturation and lightness (brightness). The setting is always 0 for each of these when you first enter the dialog. You can move the sliders through -180 to 180 for Hue, and between -100 and 100 for Saturation and Lightness. These are measured relative to the current setting. (Note that the Hue values can be imagined as being degrees on a circle, so that -180 and 180 result in the same color being selected.)

On the left of the dialog there is a list of all the colors in the RGB and CMY scales. Any one of these can be selected and changed in its hue, saturation or brightness. The default setting is Master, that is , all the colors of the image are changed together.

All the changes you make in the "Hue/Saturation" dialog are immediately applied to the image on screen. Click on OK to exit the dialog and keep the changes; otherwise click on Cancel to close the dialog and abandon the changes.
