What is the use of the Hue Saturation?

The Hue/Saturation command adjusts the hue (color), saturation (purity), and lightness of the entire image or of individual color components in an image. Use the Hue slider to add special effects, to color a black and white image (like a sepia effect), or to change the range of colors in a portion of an image.

What are the 3 dimensions of color?

How do you make a hue saturation adjustment layer?
