The default 'markeredgecolor' (or 'mec') is black, and with small dots, you
will see more edge color than face color. To test this, create the same
plot but with an exaggerated marker size, e.g. markersize=30. If that is
the problem, you can fix it by also setting the edge color to green, e.g.
mec='g'.
