In GTK 2, it's best to omit the gdk_color_alloc, and use
gdk_gc_set_rgb_fg_color() instead of gdk_gc_set_foreground().  Then
the color will come from the preexisting RGB color cube and you won't
have to worry about deallocating it.

Another handy function is gdk_color_parse(), since it will parse a
string such as "red"
