[Chartjs]-ChartJS ticks values are not correct

With the code you provided the ticks array contain the correct ticks if I try to print them normally: https://jsfiddle.net/Leelenaleee/bfc3evz1/6/.

If you want the number 2 to be red and the rest be black your best option is to update to the latest version of chart.js which means you need to use the beta of ng2-charts, then you can make use of the scriptable options.

var options = {
  type: 'line',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
      label: '# of Votes',
      data: [12, 19, 3, 5, 2, 3],
      borderColor: 'pink'
    }]
  },
  options: {
    scales: {
      y: {
        ticks: {
          color: ({
            tick
          }) => (tick.value === 12 ? 'red' : Chart.defaults.color)
        }
      }
    }
  }
}

var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<body>
  <canvas id="chartJSContainer" width="600" height="400"></canvas>
