Hi, I have been using Color Balance a lot lately (mostly due to me not yet having found out how to apply tone curves to only the red channel but that's different topic) to remove light pollution from astrophotos. It works great so far for me.
When looking at the source code I see that it translates LAB -> XYZ -> sRGB -> apply changes -> sRGB -> XYZ -> LAB I am only post processing images for a couple of months and only lately started to dive into the topic of color spaces. What I noticed is that darktable (I don't know since when) also supports ProPhoto RGB color space. And AFAIK this color space is much closer to LAB than sRGB. My question now is: would it be an improvement in terms of accuracy and "available" colors to use ProPhoto RGB instead of sRGB as an intermediate color space to apply the changes to?
