problems with gnome_lamp widget

[Justin Maurer <mike911 clark net>]

here's my code:

void makeLamp(void)
{
Lamp = gnome_lamp_new();
gtk_box_pack_start(GTK_BOX(HBox), Lamp, TRUE, TRUE, 0);
c.red = 255;
c.blue = 0;
c.green = 0;
gnome_lamp_set_color(GNOME_LAMP(Lamp), &c);
gtk_widget_show(Lamp);
}

here's my problem: 
first off - i'm using GdkColor c; and including <libgnomeui/gnome-lamp.h>,
so those aren't my problems.

no matter what values i set the three colors to, the lamp is always dark
black. i've tried 255, 100, 100, etc. none work. if i don't set them at
all, it's set to the ince neutral grey color.

any ideas?
