Sponge Brush -> affect selective color range

[robertochaves]

I'm looking for a way to easily remove redness/blemishes when doing skin retouch.
If the sponge brush had the option to select a color range.

The color range selection could work in a few ways:

1) like the Hue/Saturation dialog works, where you can pick a primary color and then select the range (bottom) and how it fades over these star and end points.
2)  similar to how Photoshop allows you to do selective color (the two last images I've included try to visualise this), I really like the radius distance option!

These sort of selections could probably be useful in many more scenarios.
