However, roughly as I suspected, Guess the original colour temperature, (say tungsten lighting 3500) and rebalance to standard RGB daylight (5500)
Amazingly, a search did bring up a Gimp help page https://docs.gimp.org/2.9/en/gimp-filter...ature.html
and I did learn something, did not know about the standard value drop down, but then not a tool I use
