How to change the label color in chart.js?

I have a pie chart defined like so,

var myChart = new Chart(ctx, {
        type: 'doughnut',
        data: {
            labels: data.labels,
            datasets: [{
                data: data.values,
                backgroundColor: [
                'rgb(255, 99, 132)',
                'rgb(54, 162, 235)',
                'rgb(255, 206, 86)',
                'rgb(75, 192, 192)',
                'rgb(153, 102, 255)',
                'rgb(255, 159, 64)',
                'rgb(204, 255, 64)',
                'rgb(64, 159, 255)',
                'rgb(175, 64, 255)'
                ],
                options: {
                    responsive : true,
                }
            }],
            fontColor : '#FFFFFF'

        }
    });

how the chart looks,

enter image description here

This however is setting the font color of the labels to black, how can I change this color. Any pointers on this is highly appreciated. Thanks!

The only solution i found to work for this problem is the following line

Chart.defaults.color = '#fff';

Hope it helps

To change label color with Chart.js, you must set the fontColor.

to set the fontColor of the labels by setting the fontColor in the options object property.

for example;

    fontColor: "white", // set color

Sorry to unbury this but trying any solutions and only this works. create plugin before chart :

Chart.plugins.register({
    beforeDraw: function(c) {
        c.legend.options.labels.fontColor = 'hsl(0,0%,85%)';
    }
});
var chart = new Chart(ctx, {
....

You can change the font color of legend­'s label, in the following way ...

options: {
   legend: {
      labels: {
         fontColor: 'white'
      }
   },
   ...
}

         backgroundColor: [
