Hue is another name for color. When an image’s hue is adjusted, the base color of that image changes in correlation with the color wheel.
The image’s saturation refers to the intensity of its colors.

How do I adjust the hue and saturation?
It is a simple task to adjust the brightness and contrast in a photograph:
1) Pull down the Layer menu.
2) Point to New Adjustment Layer. (The New Adjustment Layer will create a layer for your enhancements so the original image remains intact.)
3) Click on Hue/Saturation.
The Hue/Saturation dialog box will appear:
4) Check the Preview check box. This will show you your adjustments before you finalize them.
5) Adjust the Hue, Saturation and Lightness levels using either the slider bars or by changing the numericals values.
