[Plplot-general] Changing the color of the box drawn by plbox

I'm trying to write a small wrapper class around the c++ bindings, to be
used as a general plotting lib.  As part of the customization, I want to
be able to select the color for window, box, label, and data points.  I
have most of it working, all except for the color of the box.  No matter
what I try, it always draws red.  The relevant snippet is below.  rgb_XX
are arrays, where elements 0 1 2 hold the 8 bit color info.  I'm using
5.9.9 in Debian testing.  Thanks in advance!

    // Set device
    this->dataPlot.sdev(driver.c_str());  
   
    // Initialize a plot
    this->dataPlot.init();

    // advance the page
    this->dataPlot.adv(0);

    // Use the default viewport, let plplot make bound decisions
    this->dataPlot.vsta();   

    // Set the background color, create a window
    this->dataPlot.col0(0);
    this->dataPlot.scol0(0,
            this->rgb_bg[0],
            this->rgb_bg[1],
            this->rgb_bg[2]);   
    this->dataPlot.wind(this->x_min,
            this->x_max,
            this->y_min,
            this->y_max);

    *This is the part which I cannot get to work.
    It looks like all the others, but no luck
