Maybe I underestimate this peofiles, but I got it this way:
These profiles are made to have better matching colours when it comes to different devices. For example, a photo camera, your display and the printer. All of them will show differences for each colour in your taken pictures. A profile is used to minimize those differences so that the print is as close as it could get on your taken or edited picture colorwise.
So I think this is not the tool I am looking for. Moreover, to create my own profile i need a colorimeter to measure the colours my display is showing.











Ok, I have watched a short video to create a colour profile with RawTherapee but it was a kind of preset for internal uses. I have no clue if this can be exported. But yes, It could be difficult to achive what I am looking for and create this profile…
I have a Radeon so nVibrant is no choice.
Thank you very much for the reference even if I do not have seen shader code ever before.
