Modified again, thanks to a suggestion by Aurélien.
I made a testing version (found on my pull request
https://github.com/darktable-org/darktable/pull/3121) with 3 vibrance
sliders to compare the effects of the different formulas.
At the moment only on non-OpenCL version.
I checked the effect on
Pull request done!
First I wanted to make sure everything was okay.
Thanks again for the suggestions on the vibrance formula!

Thanks for the feedback, Aurélien!
1. I used this formula for the vibrance:
http://redqueengraphics.com/category/color-adjustments/ (it can also be
computed together with saturation).
I changed it to your proposed formula, to be consistent with other
software. It's also cleaner to have the two
Hi,
1. Vibrance is supposed to be *{ RGB } = Y + saturation * ( { RGB } - Y
)^vibrance*, where Y is the luminance channel from XYZ space, and { RGB
} a pixel vector. This way, you perform both operations at once. Also,
using (R + G + B) / 3 instead of Y is generally not a good idea since it
has

Yes, it affects colors less than Velvia. It doesn't intend to emulate film.
The results of this slider are very similar to the standalone Vibrance tool.
There are some important differences:

Is it any different from velvia iop in darktable?
