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.

It's excellent for this. Far surpasses Hus & Saturation in AE.

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. > > >Is there a way for the hue correct to work in 'video colorspace' like some of >the merges do?
