Fill function not accepting hexadecimal colors

>> A = [2 2 4 4];

>> B = [5 3 3 5];

>> fill(A,B,"blue");

Above produces expected result

>> fill(A,B,"#0000FF");

"Error using fill

Invalid color, marker, or line style."

But using "#0000FF" or any hexadecimal color throws an error. Why? Using version R2023a

patch("XData",A,"YData",B,"FaceColor","#0000FF");
