Accepted answer

you would do that the same as you did the title color change:

chart.yaxis[0].update({
    title: {
        style: {
            color: 'red'
        }
    },
    linecolor: 'red',
    linewidth: 1
});

edit - to revert the color do this:

mouseout: function () {
        chart.yaxis[0].update({
            title: {
                style: {
                    color: '#89a54e'
                }
            }
        });
}

you had the mouseout function in there but you didn't populate it.
