I’m always a little bit torn with the Blender like primaries.
Most of the times I like the results. Anyway I struggle with the colour shift in the greens. I find it somehow unpredictable and sometimes too strong.
A good example:

With Blender like primaries:
The greens shift towards red. While I think desaturating the highlights, most of the time, makes sense. But I’m not sure if I like this colour shift.
For now, I have deactivated the primaries and just use them when something is oversaturated. Maybe I try to setup my own standard primaries later on. Not decided yet.
