Using CamanJS, how can we manipulate individual color channel saturation like GIMP or Photoshop?
For example, if I decrease Red color saturation it only reduces the saturation of the Red channel. Here is the before and after image.
In GIMP there is functionality to change saturation/hue for individual colors.

Please let me know how can we achieve this using CamanJS or any other Canvas manipulation javascript library?
