Hello Dan,

System colors depends on a lot of things. 

If you're talking about a SWF application then the "active theme"
updates System.Drawing color tables with it's own color information.
However I'm not quite sure where the default theme gets it's colors. You
should ask this on the mono-winforms-list.

Otherwise (non SWF apps) System.Drawing use some default hard-coded
values that looks like a "default" windows system.
