Color Range desaturation

[ulfius]

Is there a method or a plugin that will allow me to desaturate a color range? For example, I'd like to desaturate a specific range of blues in my video. Not just one specific color, but a specific color +/- a range bordering that color.

Add your source to your scene.

Add the same source again to the scene using "Add Existing". Add each source to it's own group. I called them "Fore" and "Back".

To the lower group in the list, add a Color Correction filter and set the saturation to -1.

To the upper group add a Chroma Key filter, change the Key Color Type to Custom, and select the color you want to desaturate. The "Similarity" slider spreads the range of the hue you selected. I added a Color Correction filter to increase the saturation for a little added "pop".

Here's the final result.
