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);
