Control FILLPATTERN in Box Plot, when there is no enough Data

[SASuserlot]

I am using the following code to generate the box plot. However My carmodel with Red color have only one record.  I want to display the patterns to every Blue and Green colors, but not for the 'Red' color group . Is there any way I can control it? thank you in advance.

/* Create dataset with 20 cars - Volvo/Fiat/Land Rover forced to Red */
data car_performance;
    length CarModel $20 Color $10;
    
    /* Define car models */
    array car_models[20] $20 _temporary_ (
        "Toyota Camry", "Honda Accord", "Ford Mustang", "Chevrolet Corvette", 
        "BMW M3", "Tesla Model S", "Audi A4", "Subaru Outback", 
        "Jeep Wrangler", "Porsche 911", "Lexus RX", "Hyundai Sonata", 
        "Volkswagen Golf", "Mazda CX-5", "Mercedes C-Class", "Nissan Altima", 
        "Kia Telluride", "Volvo XC90", "Land Rover Defender", "Fiat 500"
    );
    
    /* Define colors (Green replaces Silver) */
    array colors[2] $10 _temporary_ ("Blue", "Green");
    
    /* Generate data */
    do i = 1 to 20;
        CarModel = car_models[i];
        
        /* Force Volvo, Fiat, Land Rover to Red */
        if CarModel in ("Volvo XC90", "Fiat 500", "Land Rover Defender") then 
            Color = "Red";
        /* Distribute others evenly between Blue/Green */
        else 
            Color = colors[mod(i, 2) + 1];
        
        /* Random MPG values (color-specific ranges) */
        if Color = "Red" then 
            MPG = round(18 + 12 * ranuni(0));       /* Red: 18-30 MPG */
        else if Color = "Blue" then 
            MPG = round(22 + 10 * ranuni(0));       /* Blue: 22-32 MPG */
        else 
            MPG = round(25 + 8 * ranuni(0));        /* Green: 25-33 MPG */
        
        output;
    end;
    
    drop i;
run;

data xx;
	set car_performance;
	if CARMODEL in ('Volvo XC90' 'Land Rover Defender') and color = 'Red' then delete;

And Answer is yes. but you need to polt this BOX graphc twice .

options orientation = landscape errors = 2 missing = ' ' nofmterr ls = 175 validvarname = upcase  nobyline;
ods graphics on / attrpriority=none reset=all width=9.0in height=4.6in border=off  outputfmt=png;

ods escapechar = '^';
ods results on; 
ods listing close; 
ods rtf file = "C:\temp\test.rtf" ; 
data xx1;
 set xx;
 if COLOR ne 'Red' then MPG1=MPG;
run;
proc sgplot data=xx1 noautolegend;

    title "Car MPG Distribution by Color";
	vbox MPG / category=Color 
               dataskin=none  fillattrs=(color=lightblue)
               lineattrs=(thickness=2);
    vbox MPG1 / category=Color 
               dataskin=none 
			   fillpattern nofill
               lineattrs=(thickness=2 );
    
    /* Customize colors in the plot */
    styleattrs  datafillpatterns=(X1) datacolors=(black) datacontrastcolors=(black);
    
    xaxis label="Car Color";
    yaxis label="Miles Per Gallon (MPG)" grid;
run;
ods rtf close;
