Desaturation mask not working
Hello,
I am trying to desaturate part of an image to zero percent saturation. To do it, I painted a mask at 100% opacity and set the saturation to 0%. However, the area has a strong blue green cast. Taking a look at the RGB values anywhere under the mask shows that the G and B values are about 10 units higher than R wherever it is checked.
I fixed it in Photoshop but want to fix it in Capture One. Another image in the same session had the same modification applied but no problem.
To isolate the problem, I turned off all masks except the saturation adjustment and the problem remains, so I assume the problem is in that layer. I made another layer to be sure the mask opacity was 100% but had the same result. I also checked whether the color correction or saturation sliders had an effect but these were set to zero.

Are you sure that the saturation and/or the colour balance tools on the background layer are set to default? If you add saturation on the background (say to +10) and on your masked layer to -100, the net effect will be -90. Also the overall colour may be affected by adjustments to the shadow, mid-tone or highlight controls in colour balance, and possibly (though I have not tried this) by separate adjustments to the R, G and B curves, and the R, G and B levels controls.
