Customize hAxis ticks colors in Google Bar Charts

Is it possible to change the color of the ticks on the xAxis bar?

See this image

I want to make the ticks from 2000 green, the 2500 orange and the 3000 red.

I've tried this, but it doesn't seem to work:

ticks: [500, 1000, 1500, {v: 2000, color: "Green"}, {v: 2500, color: "Orange"}, {v: 3000, color: "Red"}]

ticks: [500, 1000, 1500, [2000, "Green"], [2500, "Orange"], [3000, "Red"]]

Any help is appreciated, thank you!

there are no config options for changing the color of individual ticks

but you can change manually, on the chart's 'ready' event,
see following working snippet... 

google.charts.load('current', {
  packages: ['corechart']
}).then(function () {
  var data = new google.visualization.arrayToDataTable([
    ['Category', 'value'],
    ['a', 2924],
    ['b', 2075],
    ['c', 2516],
    ['d', 2153],
    ['e', 2348],
    ['f', 1925]
  ]);

  var container = document.getElementById('chart_div');
  var chart = new google.visualization.BarChart(container);

  google.visualization.events.addListener(chart, 'ready', changeTickColors);

  chart.draw(data, {
    legend: {
      alignment: 'end',
      position: 'top'
    },
    hAxis: {
      ticks: [500, 1000, 1500, 2000, 2500, 3000]
    }
  });

  function changeTickColors() {
    var tickColors = {
      "2,000": "green",
      "2,500": "orange",
      "3,000": "red"
    };

    Array.prototype.forEach.call(container.getElementsByTagName('text'), function(label) {
      if (label.getAttribute('text-anchor') === 'middle') {
        if (tickColors.hasOwnProperty(label.textContent)) {
          label.setAttribute('fill', tickColors[label.textContent]);
        }
      }
    });
  }
});
