I wrap 2 colourspace nodes around colour corrections sometimes,
lin to sRGB at the top
sRGB to Lin at the bottom.



I do find it sometimes helps in your situation, then again sometimes not.

Have you tried the HueCurves node? It's excellent for this. Far surpasses Hus & 
Saturation in AE.

I've got a question regarding hue correction for killing spill in nuke with 
regards to the hue correction in after effects. In after effects I am able to 
use the "hue saturation" effect to get very accurate spill corrections without 
much of a hassle by using the color range selectors to grab just the edges 
while 
tweaking the hue rotation, but in nuke I seem to have no way of grabbing the 
fine edge colors at all. I always seem to get some sort of weird edge detail 
that retains the original spill color. I don't want to assume, but I think it 
has something to do with nuke's linearization of the input image, while after 
effects does not do this.
