For a while I used color zones module too to desaturate magenta and change its hue toward orange. But I don't think it's the right way too go because it's not only a matter of saturation: some pixels in the problematic colors are ultra bright and in these zones any detail it's lost, like if it were overexposed. The workaround I've found, setting input profile to linear Rec2020 RGB, work only at the cost of losing contrast and saturation.
About profiled denoise: I use a profile which works quite good, let me know if you want to try it. The only downside it's that you need to compile DT from sources because to include denoise profile you need to edit "noiseprofile.h" file. It's not a difficult task, in the section "installation" of DT site it's explained clearly how to do it. 2015-01-02 12:37 GMT+01:00 Remy Pascal <remy.pas...@gmail.com>: > same problem here, the Magenta are far too strong.
