By the way, just to clarify, I wasn't talking about the console output, but
the window it opened up alongside (on the right), which showed the green
was darker.

In the end, I used "-colorspace fcc" which seems to have fixed the issue.
A shame we needed to research that, since it looks like fcc should be
the default, at least for a large subset of Windows systems.
