The HSL color space categorizes colors by their hue, saturation, and lightness. As in the HSV color space, Hue corresponds tothe colors around the outside of the color wheel and Saturation refers to the intensity of a color.Varying hue with 100% saturation and 50% lightness. Varying saturation with 0% hue and 50% lightness
The HSL color model allows the color to range from a color that is fully saturated to gray. The HSV goes all the way down to a white, which is not useful to many users of the color model. On the other hand, light can range from white to black in a HSL model (with the desired color in between), while the similar HSV color model can only range from the desired color to black. It is obvious that the HSL color model does indeed offer more freedom

The Hue slider will acually change the color whether its one color that you've targeted or all colors in the Master channel. Use it in conjunction with the colorize check box (bottom right) to achieve almost limitless monochromatic effects, or use it on a targeted color to alter the color temperature. For example, say you have some greenery (perhaps some ivy in the background?) that you want to make more aqua rather than warm and yellow. Make sure you're editing the greens and slide the hue slider to the right slightly. Keep in mind that this will effect all the greens in the image.
Now for the bars at the bottom of the dialog. The color bars at the bottom show your color before (the top color bar) and your color after (the bottom bar). The color inside the middle bracket (which shows up when you are targeting a specific color) is the main color that you will be affecting and the colors inside the outer brackets are used to feather your selection. You can resize any of the brackets to fine tune your selection and narrow down the color that you want to affect.
