Answer 1

I have created a simple color family with 15 different colors.
They are not randomly chosen. Instead, the colors have been chosen to maximize the difference between near colors.

You can still create the chart with less than 15 data points and no warning will be generated.

Here is the code:

ctx = document.getElementById('myChart').getContext('2d');
chart = new Chart(ctx, {
    type: 'pie',
    data: {
        datasets: [{
            label: 'Colors',
            data: [9, 8, 7, 6, 5, 4, 3, 2, 1],
            backgroundColor: ["#0074D9", "#FF4136", "#2ECC40", "#FF851B", "#7FDBFF", "#B10DC9", "#FFDC00", "#001f3f", "#39CCCC", "#01FF70", "#85144b", "#F012BE", "#3D9970", "#111111", "#AAAAAA"]
        }],
        labels: ['a','b','c','d','e','f','g','h','i']
    },
    options: {
        responsive: true,
        title:{
            display: true,
            text: "Color test"
        }
    }
});

This is the html:
