Setting the initial color of the color picker

I'm trying to set an inital color different than black for the color picker:

grapesjs.init({
    // ...
    colorPicker: { 
        color: '#3777B4',
        showAlpha: false,
        showPalette: false,
        preferredFormat: "hex",
        appendTo: 'parent', 
        offset: { 
            top: 26, 
            left: -190 
        }
    }
));

This doesn't work, even if color is a valid option.

Is there a way to set this initial color?

I'm open to solutions even if they don't use the config directly but involve some hacky code.
