Gimp Color Profile (from Rawtherapee)

Ciao @FAb7D!
The ‘correct’ reply would be:
It depends on a lot of things…
Start by studying Elle Stone's well-behaved ICC profiles and code

It is dinner time up here, but when I am back at my main computer again I will send a better reply…

Now after dinner:
Basically — if you want to export 8-bits, use RTv4_sRGB as output profile. If you want to export 16-bits, use RTv4_Large as output profile.

Also web search for Andrew Rodney’s Color Management for Photographers.
