SysML uses orange copies of UML icons ** dark orange: f46800 ** light orange: f6b200
Process to create the new icons: (Should be improved) ** Open the UML . gif with paint.net ** Change the color ** Save (now the display is correct in model explorer but not in new Diagram/Table menu) ** Open the icon with GIMP ** Export as GIF (now works in both use case)
