basecurve already applies heavy “transformations”. LR does it even more. Some very general comments from a dt user:
- Camera specific basecurves were provided by users and could not be proofen to be correct.
- basecurve and the pixelpipeline of darktable is been discussed a lot over the last year, because of various flaws, but this is maybe unrelated to your

correct colorsbut they are talking aboutpleasant colors. - I hope your screen is calibrated and you have a color managed workflow.
