AmCharts Help "Chart Tools" - Legend using a random color

I have really been struggling with AmCharts today. It seems like a great tool to visualize your data but I have experienced so many hang ups.

So currently I have 3 series that stack. I have colored them and the columns show the correct color but the legend decides it wants to do it’s own thing. Nowhere in the amcharts settings is that light green color. Why would it be using this?

ok, so figured it out.
Apparently it uses the line color for the legend and not the fill color, and if you leave it blank it has a default which doesn’t really let you know.
