Vibrance adjustment

Apply this adjustment via the Adjustments panel using the following settings:

Vibrance—controls the intensity of colors in the image without clipping them. Drag the slider to the left to reduce color intensity, drag the slider to the right to boost subtle color intensity while minimizing the over-saturation (clipping) of more intense colors. Skin tones are also preserved to retain a natural appearance.
Saturation—controls the intensity of colors in the image equally, allowing for possible clipping. Drag the slider to the left to reduce color intensity, drag the slider to the right to boost color intensity without regard to clipping, allowing for much more intense results.
