Struggling on raw blue color saturation

[Nor_man]

IMHO It’s definitly the standard color matrix in Input Color Profile causing this problem. (in combination with basecurve)

Thats the reason I calibrated my camera with darktable-chart and use Rec2020 as Input Color Profile to get nice color:

Profiling a camera with darktable-chart

Hi, I have used IT8 Target by Wolf Faust to create styles which look like the camera jpg processing of my Olympus OM-D EM5 II. One important thing for me: I used Rec2020 as Input color profile. this way i get much better (natural) color in dark blue. I think standard matrix is “blowing out” extreme colors when you shoot in extreme light conditions (disco, concert…) https://dtstyle.net/index.php/a/Norman%20Schülke (just the last for EM5 II) Its a good Starting Point for Olympus OM-D cameras …

there are some styles on https://dtstyle.net/ for Fuji cameras. did you try those?
