Setting Up a Gadget's Background Colour: <fgcol>

Some gadgets allow their background color to be set in their definition, using the <fgcol> graph.

>-- <fgcol> --+-- BACKGround --.

              ‘-- SETColour ---‘-- <colno> -->

Where, "<colno>" allows an integer color index number, a color name, and various application color synonyms, including FORM (the default F&M simple dialog form background color).
