I would avoid using the paint tools (like fill) and head right to either
levels or curves.

Try Levels and the Auto Input button and then work from there, using the
gamma
slider (the triangle in the middle) and not with the Value, but on the
color channels
which can be found in the menu that defaults to Value.

Have one of the desired photos open and twiddle with especially green and
red gamma
until they look similar.

Others have reported good luck also with the Channel Mixer plug-in which
should also
work if harnessed correctly for the task, but I have a particular fondness
for the Levels
Tool and when attempting such repairs with the Channel Mixer, quickly
return to the tool.

Let us know how it goes?
