FVWM: Widget fg color

[Ingo Wardinski]

Hi all,
I try to set a widget foreground color to differ from the default, i.e. 

WindowTitle     {Weather_applet}
WindowSize      210 210
WindowPosition  1038 634
Colorset        12
Widget                  1
Property
        Type            ItemDraw
        Size            100 15
        Position        71 82
        Font            "shadow=0 se:xft:sans:size=7:antialias=True"
        Flags           NoFocus NoReliefString Left
        ForeColor       { orange }
Main
Case message of
        SingleClic:
        Begin
                Quit
        End
End
where the default is defined by coloset 9 
Colorset 9 fg #ffffff, bg #f1eee0, hi #f1eee0, sh #f1eee0, fgsh #f1eee0, Tint 
black 35, RootTransparent

However, fvwm(-2.5.23) is complaining: Cannot parse color " orange "
What does that mean, and more generally, how can I set up a widget fg
color differently from the default? 

TIA
