sorry i can't reproduce the change of hue that you are seeing - in any of my current pictures, when i reduce red (in Ps) the picture just looks less red - i haven't used nx2/nikon since the 900 came along and upset various applecarts -
the short answer ...
… yes more or less, but for me not in raw - at this stage of final adjustments i'm in Ps and tiff and i'm doing what your understanding is above -
ie. a recent perfectly fine prophoto tiff, in order to avoid srgb conversion dark clipping, the black levels in r&g needed to be set at 25 units and in b at 38 - then the very small resulting lower levels had to be compressed via curves to bring the look back (…sigh, what i do for a beautiful waveform)
a longer answer …
for my raw processing i output a picture with nothing clipping even if the look is not the way i finally want it, although i try to make the exposure close to being overall correct (best done in raw i think - although once in Ps i sometimes do radical changes for DR, zonal contrast and re-exposure for dark parts - there is a lot of info available in my files that can be brought out or hidden by contrast curves alone) -
i use C1 for my raw processing (it does almost all of what i want but not totally (yet) and Ps is familiar for me) - so in raw, once the exposure is the way i want it, i then bring the overall black levels up or the whites down to unclip anything that might still be a problem - so a tiff file comes out with everything available for lossless adjustment even though the picture at this stage might look pale with low contrast -
- if the shot is for the web the tiff output to Ps is in srgb - or in prophoto or adobe for prints -
then, in srgb, tweaks (levels, curves, colours, contrast masking etc) are no problem -
however, in adobe/prophoto tweaking for the most beautiful print ever, a conversion back to srgb might introduce clipping … to see what i then do, see the shorter answer above - hope this makes sense -
……. and having said all that, puff puff … take care with red, it's a dark colour and doesn't take kindly to being over saturated <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wub.gif' class='bbc_emoticon' alt=':wub:' />

Thank you very much for your very detailed response! I think I need more practice to see the effect.
Best regards,
