Set overall color saturation

 In the Presence area of the Basic panel, change the color saturation (vividness or color purity) of all colors by adjusting the Clarity, Vibrance, and Saturation controls. (To adjust saturation for a specific range of colors, use the controls in the HSL/Color/Grayscale panel.)
Clarity
Adds depth to an image by increasing local contrast. When using this setting, it is best to zoom in to 100% or greater. To maximize the effect, increase the setting until you see halos near the edge details of the image, and then reduce the setting slightly.

Vibrance
Adjusts the saturation so that clipping is minimized as colors approach full saturation, changing the saturation of all lower-saturated colors with less effect on the higher-saturated colors. Vibrance also prevents skin tones from becoming over saturated.

Saturation
Adjusts the saturation of all image colors equally from –100 (monochrome) to +100 (double the saturation).
