In SW03 there is a new icon called "Line Color" it is located on your line format toolbar (not there by default). If you add your fill then click that icon you can change the color right there.
Or
You can place it on a layer to change the color as well. Really this is only useful if your and old AutoCAD user that still uses layers..or..You export to AutoCAD still.
I hope that helps, Scott Baugh, CSWP
