saturation makes your color more vibrant or increase the depth. if you see that pic, red is more vibrant but it affecting the neck also.
@ rage, you need to reduce the saturation; just see the neck, saturation clearly visible there.
I used paint.net to duplicate layer and then convert upper layer to B&W and just erased away, didn't take long with variable size eraser. Not gonna work for abstract figures though.1st pic:- how did you converted into selective color, layer masking?
