    I assume you want a PseudoColor Visual. What I do is

        FL_IOPT forms_options;

        forms_options.depth = 8;
        forms_options.vclass = PseudoColor;
        fl_set_defaults( FL_PDVisual |
                         FL_PDDepth,
                         &forms_options );

    and that works for me on -- coincidentally on an Ultra 60.
