Given that "green" is used as the background color in some places,
e.g. for the boxes containing the names of heads, and that the general
scheme is dark foreground on light background, I agree that #008000 is
too dark in those places.

Purple is only used for octopus merges.  I'd like to think of a better
way to use color in representing octopus merges if possible.

Indeed.  Some people prefer to have all their windows to have light
foregrounds on dark backgrounds, so they would also benefit from
having more of the colors customizable.
