Use those predifined varibles:
white_color
dark_color
black_color
white_background
dark_background
black_background
transparent_background

document.head.querySelector('[rel="icon"]').href = getSVGDataURL( white_color, transparent_background );

document.head.querySelector('[rel="icon"]').href = getSVGDataURL( black_color, white_background);
