Vibrance
Changes in vibrancy should be made with great consideration if your goal is to retain accurate color reproduction—a little goes a long way.
A Comparison of Saturation Settings
In this example, the slight (+10) increase gives the image a very subtle boost in color purity (vibrance) without damaging the delicate, less saturated colors. This comparison shows that too much increase or decrease in vibrance can damage the image’s tonal relationships—if you are aiming for accurate color reproduction. Saturation’s effect is even more dramatic. Vibrance and saturation adjustments can also be used for special effects and non-nominal color balances.
That's it! Once you have run through the sequence of these corrections, it gets easier and easier. I recommend that you build an Action that can create all six adjustment layers in the proper modes with just three keystrokes.
