Send success messages as Color.LightGreen

Basically Color.Green looks ugly and Color.LightGreen looks less ugly. I
could see changing the default to something like pure green, but I think
this might cause people to be like "yo why is this so bright."

Now arguably this should be configurable but I'm not going to
revolutionize the world by abandoning far more important work to allow
more artful messages. I just think that Color.Green is ugly enough that
I can't tolerate it.
