Fair enough. Then again, my initial remark was in reply to the quote. If you feel the interface or behaviour of dt is incorrect, you have two options:
- convince one or more of the developers something has to change (and ideally, how it should change)
- code the changes yourself (up to forking the program), this is basically what Aurélien Pierre did when he developed filmic and several other modules (and forked to create Ansel).
In this particular case, the best you can hope for is a small change in color balance rgb. Even that is not guaranteed, as the different parts of that module can interact, so a simple soft limit on a slider may be either not enough or too much.
There is (in my opinion, of course) no reason to change filmic in any way to solve this problem.
At the end, darktable gives you a lot of control over what you can do with your images. That also means that you can use settings that are theoretically incorrect, but in some cases allow an effect you want. Or it blows up in your face…
