You can use a scriptable option for the backgroundColor for this:

const randomNum = () => Math.floor(Math.random() * (235 - 52 + 1) + 52);
const randomRGB = () => `rgb(${randomNum()}, ${randomNum()}, ${randomNum()})`;

const options = {
  type: 'pie',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
      label: '# of Votes',
      data: [12, 19, 3, 5, 2, 3],
      backgroundColor: () => (randomRGB())
    }]
  },
  options: {}
}

const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
