When adjusting the saturation in the Hue/Saturation/Value Node, it should use luminance instead of value

This guy brings up a very interesting point:

I was always confused as to why when trying to color correct a video, the Hue/Sat/Value node ruined my colors. The fix is quite simple, using RGB to BW and a mix node, but far from intuitive.

  1. HSV is not HSL. Removing saturatuon is not removing color dept.
  2. There is no «true method» for desaturation. Photoshop have manual channel mixer for it. And with nodes it looks like this

doesn` matter now. 3.3 have separate node, that allows to make HSL channels
