Thanks for pointing that out. You are indeed correct. However, from what I can see DaVinci's tools still have the edge. With Capture One the feedback on what hues have been selected is far vaguer than I would like. Moreover, the node-based workflow is far more suitable for complex adjustments.

Repeating a point I made in another comment: in DV it is possible to edit hue to hue, hue to saturation, hue to luminesce, luminesce to saturation, saturation to saturation and saturation to luminesce. There is also the amazing chroma warp, using which near arbitrary color adjustments can be made. Nothing out there comes even close to that capability. No wonder most Hollywood movies are color graded in DV.
