    * A color well is a widget which controls color settings.
    * Colors may be dragged and dropped from one color well to another.
    * A double-click inside a color well will bring up the standard
    * color dialog panel to edit the color well's color.
    * Colors may be also pasted by name using middle-mouse click into/out of
    * color wells from/to other selection-capable applications; for example,
    * you can highlight the word `red' and paste it into a color well.
    * While the color value is being changed, the color well sends a SEL_CHANGED
    * to its target; at the end of the change, it sends a SEL_COMMAND.
    * The message data represents the current color value, of the type FXColor.
