For me it works -- I open color zones, choose the saturation tab,
increase saturation for the blues by about 2 units, and move the other
color sliders a bit so that the increase is limited to the blues.

As in the example on fstoppers, this increases blue saturation, (look
for the blue shirt in their example), but also overall color contrast
impression.

An somehow similar way to increase color contrast in darktable is the
equalizer. I like to add a small bump to the middle of the chrominance
tab there. That keeps the color balance, but it might make reddish
faces worse, while the blue saturation doesn't.

Cheers

Michael
