 This is a very simple script to use:

 - use the color picker to set the foreground color from some part of the
 picture that should be grey or white.
 - call filter,
 - done.

 The colortemperature script by the same author is also a good catch.

Thanks for your quick help.
I imported both scripts. After trying the script colortemp was the good one.
Again, thanks.

Just in case, you can use colortemp interactively via experimental
GEGL tool (Tools  GEGL operation menu). This will draw preview
right on canvas. For a large image this can be too slow, so you can
temporarily resize, find the best setting, undo resizing and apply
same operation with preview disabled.
